Sphingosine-1-phosphatase is an intracellular enzyme located in the endoplasmic reticulum, which regulates the level of sphingosine-1-phosphate (S1P), a bioactive lipid.

Several members of this family have been annotated as bacitracin transport permeases, as it was suspected that they form the permease component of an ABC transporter system. It was shown, however, that BcrC from Bacillus subtilis posesses undecaprenyl pyrophosphate (UPP) phospatase activity, and it is hypothesized that it competes with bacitracin for UPP, increasing the cell's resistance to bacitracin.

Lipid A 1-phosphatase, or LpxE from Francisella novicida selectively dephosphorylates lipid A at the 1-position. Lipid A is the membrane-anchor component of lipopolysaccharides (LPS), the major constituents of the outer membrane in many gram-negative bacteria.

PAP2 is a super-family of phosphatases and haloperoxidases. This subgroup, which is specific to bacteria and archaea, lacks functional characterization and may act as a membrane-associated lipid phosphatase.
Dolichyldiphosphatase is a membrane-associated protein located in the endoplasmic reticulum and hydrolyzes dolichyl pyrophosphate, as well as dolichylmonophosphate at a low rate. The enzyme is necessary for maintaining proper levels of dolichol-linked oligosaccharides and protein N-glycosylation, and might play a role in re-utilization of the glycosyl carrier lipid for additional rounds of lipid intermediate biosynthesis after its release during protein N-glycosylation reactions.
Glucose-6-phosphatase converts glucose-6-phosphate into free glucose and is active in the lumen of the endoplasmic reticulum, where it is bound to the membrane. The generation of free glucose is an important control point in metabolism, and stands at the end of gluconeogenesis and the release of glucose from glycogen. Deficiency of glucose-6-phosphatase leads to von Gierke's disease.

>cd03383 PAP2_diacylglycerolkinase PAP2_like proteins, diacylglycerol_kinase like sub-family
In some prokaryotes, PAP2_like phosphatase domains appear fused to E. coli DAGK-like trans-membrane diacylglycerol kinase domains. The cellular function of these architectures remains to be determined.
>cd03390 PAP2_containing_1_like PAP2, subfamily similar to human phosphatidic_acid_phosphatase_type_2_domain_containing_1
Most likely membrane-associated phosphatidic acid phosphatases. Plant members of this group are constitutively expressed in many tissues and exhibit both diacylglycerol pyrophosphate phosphatase activity as well as phosphatidate (PA) phosphatase activity, they may have a more generic housekeeping role in lipid metabolism.

Most likely a family of membrane associated phosphatidic acid phosphatases. Wunen is a drosophila protein expressed in the central nervous system, which provides repellent activity towards primordial germ cells (PGCs), controls the survival of PGCs and is essential in the migration process of these cells towards the somatic gonadal precursors.

>cd01610 PAP2_like PAP2_like proteins, a super-family of histidine phosphatases and vanadium haloperoxidases, includes type 2 phosphatidic acid phosphatase or lipid phosphate phosphatase (LPP), Glucose-6-phosphatase, Phosphatidylglycerophosphatase B and bacterial acid phosphatase, vanadium chloroperoxidases, vanadium bromoperoxidases, and several other mostly uncharacterized subfamilies
These enzymes catalyze phosphomonoester hydrolysis, with optimal activity in low pH conditions. They are secreted into the periplasmic space, and their physiological role remains to be determined.
>PF01569 PAP2: PAP2 superfamily This family includes the following Prosite family; InterPro: IPR000326 This entry represents type 2 phosphatidic acid phosphatase (PAP2; 3
1.3.4 from EC) enzymes, such as phosphatidylglycerophosphatase B 3.1.3.27 from EC from Escherichia coli. PAP2 enzymes have a core structure consisting of a 5-helical bundle, where the beginning of the third helix binds the cofactor []. PAP2 enzymes catalyse the dephosphorylation of phosphatidate, yielding diacylglycerol and inorganic phosphate []. In eukaryotic cells, PAP activity has a central role in the synthesis of phospholipids and triacylglycerol through its product diacylglycerol, and it also generates and/or degrades lipid-signalling molecules that are related to phosphatidate. Other related enzymes have a similar core structure, including haloperoxidases such as bromoperoxidase (contains one core bundle, but forms a dimer), chloroperoxidases (contains two core bundles arranged as in other family dimers), bacitracin transport permease from Bacillus licheniformis, glucose-6-phosphatase from rat. The vanadium-dependent haloperoxidases exclusively catalyse the oxidation of halides, and act as histidine phosphatases, using histidine for the nucleophilic attack in the first step of the reaction []. Amino acid residues involved in binding phosphate/vanadate are conserved between the two families, supporting a proposal that vanadium passes through a tetrahedral intermediate during the reaction mechanism.; GO: 0003824 catalytic activity, 0016020 membrane; PDB: 1QI9_B 1IW8_A 1EOI_A 1D2T_A 1QHB_D 1UP8_C 2IPB_A 1VNS_A 1VNF_A 1VNE_A ....
Haloperoxidases catalyze the oxidation of halides such as bromide or chloride by hydrogen peroxide, which results in subsequent halogenation of organic substrates, or halide-assisted disproportionation of hydrogen peroxide forming dioxygen. They are likely to participate in the biosynthesis of halogenated natural products, such as volatile halogenated hydrocarbons, chiral halogenated terpenes, acetogenins and indoles.
Yeast Aur1p or Ipc1p is necessary for the addition of inositol phosphate to ceramide, an essential step in yeast sphingolipid synthesis, and is the target of several antifungal compounds such as aureobasidin.
