>gnl|CDD|239582 cd03505, Delta9-FADS-like, The Delta9 Fatty Acid Desaturase
(Delta9-FADS)-like CD includes the delta-9 and delta-11
acyl CoA desaturases found in various eukaryotes
including vertebrates, insects, higher plants, and
fungi. 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 insertion of a cis double bond
between carbons 9 and 10 of the saturated fatty acyl
substrates, palmitoyl (16:0)-CoA or stearoyl (18:0)-CoA,
yielding the monoenoic products palmitoleic (16:l) or
oleic (18:l) acids, respectively. In cyanobacteria, the
biosynthesis of unsaturated fatty acids is initiated by
delta 9 acyl-lipid desaturase (DesC) which introduces
the first double bond at the delta-9 position of a
saturated fatty acid that has been esterified to a
glycerolipid. 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: HXXXXH, HXXHH, and H/QXXHH. These 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. Some
eukaryotic (Fungi, Euglenozoa, Mycetozoa, Rhodophyta)
desaturase domains have an adjacent C-terminal
cytochrome b5-like domain.

>gnl|CDD|238511 cd01060, Membrane-FADS-like, The membrane fatty acid desaturase
(Membrane_FADS)-like CD includes membrane FADSs, alkane
hydroxylases, beta carotene ketolases (CrtW-like),
hydroxylases (CrtR-like), and other related proteins.
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.

at the vacuole membrane, a location which is consistent
with its involvement in vacuole morphology and
inheritance. Vac7 has been shown to function as an
upstream regulator of the Fab1 lipid kinase pathway. The
Fab1 lipid kinase pathway is important for correct
regulation of membrane trafficking events.

>gnl|CDD|198375 cd07809, FGGY_D-XK_1, D-xylulose kinases, subgroup 1; members of
the FGGY family of carbohydrate kinases. This subgroup
is composed of D-xylulose kinases (XK, also known as
xylulokinase; EC 2.7.1.17) from bacteria and eukaryota.
They share high sequence similarity with Escherichia
coli xylulokinase (EcXK), which catalyzes the
rate-limiting step in the ATP-dependent phosphorylation
of D-xylulose to produce D-xylulose 5-phosphate (X5P)
and ADP. Some uncharacterized sequences are also
included in this subfamily. EcXK exists as a dimer. Each
monomer consists of two large domains separated by an
open cleft that forms an active site. This model
includes both the N-terminal domain, which adopts a
ribonuclease H-like fold, and the structurally related
C-terminal domain. The presence of Mg2+ or Mn2+ might be
required for catalytic activity. Members of this
subgroup belong to the FGGY family of carbohydrate
kinases.
