The expression of these proteins appears to be temperature dependent: decreases in temperature result in increased levels of fatty acid desaturation within membrane lipids subsequently altering cell membrane fluidity. An important enzyme for the production of polyunsaturates in plants is the oleate delta-12 desaturase (Arabidopsis FAD2) of the endoplasmic reticulum. This enzyme accepts l-acyl-2-oleoyl-sn-glycero-3-phosphocholine as substrate and requires NADH:cytochrome b oxidoreductase, cytochrome b, and oxygen for activity. FAD2 converts oleate(18:1) to linoleate (18:2) and is closely related to oleate 12-hydroxylase which catalyzes the hydroxylation of oleate to ricinoleate. Plastid-bound desaturases (Arabidopsis delta-12 desaturase (FAD6), omega-3 desaturase (FAD8), omega-6 desaturase (FAD6)), as well as, the cyanobacterial thylakoid-bound FADSs require oxygen, ferredoxin, and ferredoxin oxidoreductase for activity. As in higher plants, the cyanobacteria delta-12 (DesA) and omega-3 (DesB) FADSs desaturate oleate (18:1) to linoleate (18:2) and linoleate (18:2) to linolenate (18:3), respectively. Omega-3 (DesB/FAD8) and omega-6 (DesD/FAD6) desaturases catalyze reactions that introduce a double bond between carbons three and four, and carbons six and seven, respectively, from the methyl end of fatty acids. As with other members of this superfamily, this domain family has extensive hydrophobic regions that would be capable of spanning the membrane bilayer at least twice. Comparison of sequences also reveals the existence of three regions of conserved histidine cluster motifs that contain eight histidine residues: HXXXH, HXX(X)HH, and HXXHH. These histidine residues are reported to be catalytically essential and proposed to be the ligands for the iron atoms contained within the homologue, stearoyl CoA desaturase. Mutation of any one of four of these histidines in the Synechocystis delta-12 acyl-lipid desaturase resulted in complete inactivity. Length = 222

They are present in all groups of organisms with the exception of archaea. Membrane FADSs are non-heme, iron-containing, oxygen-dependent enzymes involved in regioselective introduction of double bonds in fatty acyl aliphatic chains. They play an important role in the maintenance of the proper structure and functioning of biological membranes. Alkane hydroxylases are bacterial, integral-membrane di-iron enzymes that share a requirement for iron and oxygen for activity similar to that of membrane FADSs, and are involved in the initial oxidation of inactivated alkanes. Beta-carotene ketolase and beta-carotene hydroxylase are carotenoid biosynthetic enzymes for astaxanthin and zeaxanthin, respectively. This superfamily domain has extensive hydrophobic regions that would be capable of spanning the membrane bilayer at least twice. Comparison of these sequences also reveals three regions of conserved histidine cluster motifs that contain eight histidine residues: HXXX(X)H, HXX(X)HH, and HXXHH (an additional conserved histidine residue is seen between clusters 2 and 3). Spectroscopic and genetic evidence point to a nitrogen-rich coordination environment located in the cytoplasm with as many as eight histidines coordinating the two iron ions and a carboxylate residue bridging the two metals in the Pseudomonas oleovorans alkane hydroxylase (AlkB). In addition, the eight histidine residues are reported to be catalytically essential and proposed to be the ligands for the iron atoms contained within the rat stearoyl CoA delta-9 desaturase.

It has been proposed that MocD, MocE (Rieske-like ferredoxin), and MocF (ferredoxin reductase) under the regulation of MocR, act in concert to form a ferredoxin oxygenase system that demethylates 3-O-MSI to form scyllo-inosamine. This domain family appears to be structurally related to the membrane fatty acid desaturases and the alkane hydroxylases.

These desaturases are required for the synthesis of highly unsaturated fatty acids (HUFAs), which are mainly esterified into phospholipids and contribute to maintaining membrane fluidity. While HUFAs may be required for cold tolerance in bacteria, plants and fish, the primary role of HUFAs in mammals is cell signaling. These enzymes are described as front-end desaturases because they introduce a double bond between the pre-exiting double bond and the carboxyl (front) end of the fatty acid. Various substrates are involved, with both acyl-coenzyme A (CoA) and acyl-lipid desaturases present in this CD. Acyl-lipid desaturases are localized in the membranes of cyanobacterial thylakoid, plant endoplasmic reticulum (ER), and plastid; and acyl-CoA desaturases are present in ER membrane. ER-bound plant acyl-lipid desaturases and acyl-CoA desaturases require cytochrome b5 as an electron donor. Most of the eukaryotic desaturase domains have an adjacent N-terminal cytochrome b5-like domain. This domain family has extensive hydrophobic regions that would be capable of spanning the membrane bilayer at least twice. Comparison of sequences also reveals the existence of three regions of conserved histidine cluster motifs that contain the residues: HXXXH, HXX(X)HH, and Q/HXXHH.

Carotenoids are important natural pigments; zeaxanthin and lutein are the only dietary carotenoids that accumulate in the macular region of the retina and lens. It is proposed that these carotenoids protect ocular tissues against photooxidative damage. CrtR does not show overall amino acid sequence similarity to the beta-carotene hydroxylases similar to CrtZ, an astaxanthin biosynthetic beta-carotene hydroxylase. However, CrtR does show sequence similarity to the green alga, Haematococcus pluvialis, beta-carotene ketolase (CrtW), which converts beta-carotene to canthaxanthin. Sequences of the CrtR_beta-carotene-hydroxylase domain family, as well as, the CrtW_beta-carotene-ketolase domain family appear to be structurally related to membrane fatty acid desaturases and alkane hydroxylases. They all share in common extensive hydrophobic regions that would be capable of spanning the membrane bilayer at least twice.

The expression of these proteins appears to be temperature dependent: decreases in temperature result in increased levels of fatty acid desaturation within membrane lipids subsequently altering cell membrane fluidity. An important enzyme for the production of polyunsaturates in plants is the oleate delta-12 desaturase (Arabidopsis FAD2) of the endoplasmic reticulum. This enzyme accepts l-acyl-2-oleoyl-sn-glycero-3-phosphocholine as substrate and requires NADH:cytochrome b oxidoreductase, cytochrome b, and oxygen for activity. FAD2 converts oleate(18:1) to linoleate (18:2) and is closely related to oleate 12-hydroxylase which cat

It has been proposed that MocD, MocE (Rieske-like ferredoxin), and MocF (ferredoxin reductase) under the regulation of MocR, act in concert to form a ferredoxin oxygenase system that demethylates 3-O-MSI to form scyllo-inosamine. This domain family appears to be structurally related to the membrane fatty acid desaturases and the alkane hydroxylases. They all share in common extensive hydrophobic regions that would be capable of spanning the membrane bilayer at least twice. Comparison of sequences also reveals the existence of three regions of conserved histidine cluster motifs that contain eight histidine residues: HXXXH, HXXHH, and HXXHH.

Carotenoids are important natural pigments produced by many microorganisms and plants. Astaxanthin is reported to be an antioxidant, an anti-cancer agent, and an immune system stimulant. A number of bacteria and green algae can convert beta-carotene into astaxanthin by using several ketocarotenoids as intermediates and CrtW and a beta-carotene hydroxylase (CrtZ). CrtW initially converts beta-carotene to canthaxanthin via echinenone, and CrtZ initially mediates the conversion of beta-carotene to zeaxanthin via beta-cryptoxanthin. After a few more intermediates are formed, CrtW and CrtZ act in combination to produce astaxanthin. Sequences of this domain family appear to be structurally related to membrane fatty acid desaturases and alkane hydroxylases. Th

Carotenoids are important natural pigments; zeaxanthin and lutein are the only dietary carotenoids that accumulate in the macular region of the retina and lens. It is proposed that these carotenoids protect ocular tissues against photooxidative damage. CrtR does not show overall amino acid sequence similarity to the beta-carotene hydroxylases similar to CrtZ, an astaxanthin biosynthetic beta-carotene hydroxylase. However, CrtR does show sequence similarity to the green alga, Haematococcus pluvialis, beta-carotene ketolase (CrtW), which converts beta-carotene to canthaxanthin. Sequences of the CrtR_beta-carotene-hydroxylase domain family, as well as, the CrtW_beta-carotene-ketolase domain family appear to be structurally related

Sequences of this domain family appear to be structurally related to membrane fatty acid desaturases and alkane hydroxylases. They all share in common extensive hydrophobic regions that would be capable of spanning the membrane bilayer at least twice. Comparison of these sequences also reveals three regions of conserved histidine cluster motifs that contain eight histidine residues: HXXXH, HXXHH, and HXXHH. These histidine residues are reported to be catalytically essential and proposed to be the ligands for the iron atoms contained within homologs, stearoyl CoA desaturase and alkane hydroxylase.

Dihydrorhizobitoxine desaturase is reported to be involved in the final step of rhizobitoxine biosynthesis. This domain family appears to be structurally related to the membrane fatty acid desaturases and the alkane hydroxylases. They all share in common extensive hydrophobic regions that would be capable of spanning the membrane bilayer at least twice. Comparison of sequences also reveals the existence of three regions of conserved histidine cluster motifs that contain eight histidine residues: HXXXH, HXX(X)HH, and HXXHH. These histidine residues are reported to be catalytically essential and proposed to be the ligands for the iron atoms contained within homologs, stearoyl CoA desaturase and alkane hydroxylase.

; InterPro: IPR005804 Fatty acid desaturases are enzymes that catalyse the insertion of a double bond at the delta position of fatty acids. There seem to be two distinct families of fatty acid desaturases which do not seem to be evolutionary related. Family 1 is composed of: Stearoyl-CoA desaturase (SCD) (1.14.19.1 from EC) []. Family 2 is composed of: Bacterial fatty acid desaturases. Plant stearoyl-acyl-carrier-protein desaturase (1.14.19.1 from EC) [], this enzyme catalyzes the introduction of a double bond at the delta(9) position of steraoyl-ACP to produce oleoyl-ACP. This enzyme is responsible for the conversion of saturated fatty acids to unsaturated fatty acids in the synthesis of vegetable oils. Cyanobacterial DesA [], an enzyme that can introduce a second cis double bond at the delta(12) position of fatty acid bound to membranes glycerolipids. DesA is involved in chilling tolerance; the phase transition temperature of lipids of cellular membranes being dependent on the degree of unsaturation of fatty acids of the membrane lipids. This entry contains fatty acid desaturases belonging to Family 1. ; GO: 0006629 lipid metabolic process

These desaturases are required for the synthesis of highly unsaturated fatty acids (HUFAs), which are mainly esterified into phospholipids and contribute to maintaining membrane fluidity. While HUFAs may be required for cold tolerance in bacteria, plants and fish, the primary role of HUFAs in mammals is cell signaling. These enzymes are described as front-end desaturases because they introduce a double bond between the pre-exiting double bond and the carboxyl (front) end of the fatty acid. Various substrates are involved, with both acyl-coenzyme A (CoA) and acyl-lipid desaturases present in this CD. Acyl-lipid desaturases are localized in the membranes of cyanobacterial thylakoid, plant endoplasmic reticulum (ER), and plastid; an

They are present in all groups of organisms with the exception of archaea. Membrane FADSs are non-heme, iron-containing, oxygen-dependent enzymes involved in regioselective introduction of double bonds in fatty acyl aliphatic chains. They play an important role in the maintenance of the proper structure and functioning of biological membranes. Alkane hydroxylases are bacterial, integral-membrane di-iron enzymes that share a requirement for iron and oxygen for activity similar to that of membrane FADSs, and are involved in the initial oxidation of inactivated alkanes. Beta-carotene ketolase and beta-carotene hydroxylase are carotenoid biosynthetic enzymes for astaxanthin and zeaxanthin, respectively.

The alk genes in Pseudomonas oleovorans encode conversion of alkanes to acyl CoA. The alkane omega-hydroxylase (AlkB) system is responsible for the initial oxidation of inactivated alkanes. It is a three-component system comprising a soluble NADH-rubredoxin reductase (AlkT), a soluble rubredoxin (AlkG), and the integral membrane oxygenase (AlkB). AlkB utilizes the oxygen rebound mechanism to hydroxylate alkanes. This mechanism involves homolytic cleavage of the C-H bond by an electrophilic metal-oxo intermediate to generate a substrate-based radical. As with other members of this superfamily, this domain family has extensive hydrophobic regions that would be capable of spanning the membrane bilayer at least twice. The active

The delta-9 acyl-lipid desaturases are found in a wide range of bacteria. These enzymes play essential roles in fatty acid metabolism and the regulation of cell membrane fluidity. Acyl-CoA desaturases are the enzymes involved in the CoA-bound desaturation of fatty acids. Mammalian stearoyl-CoA delta-9 desaturase is a key enzyme in the biosynthesis of monounsaturated fatty acids, and in yeast, the delta-9 acyl-CoA desaturase (OLE1) reaction accounts for all de nova unsaturated fatty acid production in Saccharomyces cerevisiae. These non-heme, iron-containing, ER membrane-bound enzymes are part of a three-component enzyme system involving cytochrome b5, cytochrome b5 reductase, and the delta-9 fatty acid desaturase. This complex catalyzes the NADH- and oxygen-dependent i
