Description: sn-Glycero-3-phosphocholine (GPC) is a choline derivative and one of the two major forms of choline storage (along with phosphocholine) in the cytosol. Glycerophosphorylcholine is also osmolyte. GPC is an intermediate of glycerophospholipid metabolism. It is converted from both 2-acyl-sn-glycero-3-phosphocholine and 1-acyl-sn-glycero-3-phosphocholine by lysophospholipase L2 (EC:3.1.1.5). It is converted to choline and sn-glycerol 3-phosphate by glycerophosphodiester phosphodiesterase (EC:3.1.4.46). (KEGG)

Description: Sn-glycero-3-phosphoethanolamine is a substrate for: Lysoplasmalogenase.

Description: Glycerophosphoserine is a phosphodiester. Glycerophosphoserine is a source of phosphate and glycerol for bacteria. Pseudomonas aeruginosa cytosolic glycerophosphodiester phosphodiesterase, UgpQ has broad substrate specificity toward various glycerophosphodiesters, producing sn-glycerol-3-phosphate and the corresponding alcohols. UgpQ accumulates under conditions of phosphate starvation, suggesting that it allows the utilization of glycerophosphodiesters as a source of phosphate. Pseudomonas aeruginosa possesses two systems the salvage of glycerophosphoryl diesters, the Glp system and the Ugp system. In the Glp system, the glpQ gene encodes a periplasmic glycerophosphoryl diester phosphodiesterase (periplasmic GDP) which hydrolyzes deacylated phospholipids to an alcohol and sn-glycerol-3-phosphate. The latter is then transported into the cell by the GlpT transporter. Periplasmic GDP is specific for the glycerophospho- moiety of the substrate, while the alcohol can be any one of several alcohols. This provides the cell with the capability of channeling a wide variety of glycerophosphodiesters into the glpQT-encoded dissimilatory system. In the Ugp system the diesters are hydrolyzed during transport at the cytoplasmic side of the inner membrane to sn-glycerol-3-phosphate and an alcohol by a cytoplasmic GDP, an enzyme encoded by the ugpQ gene. The Ugp system is induced when the cells are starved for inorganic phospate, which is generates phosphate by the system. In Pseudomonas aeruginosa sn-glycerol-3-phosphate can be further metabolized to dihydroxyacetone phosphate by either of two membrane-bound enzymes, depending on the growth conditions. The presumed role of this process is the salvage of glycerol and glycerol phosphates generated by the breakdown of phospholipids and triacylglycerol.

Description: UDP-N-acetyl-alpha-D-muramoyl-L-alanyl-gamma-D-glutamyl-meso-2,6-diaminopimeloyl-D-alanyl-D-alanine is an intermediate in peptidoglycan biosynthesis I (meso-diaminopimelate containing) in E.coli. It is a substrate for the enzyme phospho-N-acetylmuramoyl-pentapeptide transferase which catalyzes the reaction UDP-N-acetyl-alpha-D-muramoyl-L-alanyl-gamma-D-glutamyl-meso-2,6-diaminopimeloyl-D-alanyl-D-alanine + di-trans,octa-cis-undecaprenyl phosphate -> undecaprenyldiphospho-N-acetylmuramoyl-L-alanyl-gamma-D-glutamyl-meso-2,6-diaminopimeloyl-D-alanyl-D-alanine + UMP. It is also a product for enzyme D-alanyl-D-alanine-adding enzyme which catalyzes reaction D-alanyl-D-alanine + UDP-N-acetyl-alpha-D-muramoyl-L-alanyl-gamma-D-glutamyl-meso-2,6-diaminopimelate + ATP ??UDP-N-acetyl-alpha-D-muramoyl-L-alanyl-gamma-D-glutamyl-meso-2,6-diaminopimeloyl-D-alanyl-D-alanine + ADP + phosphate + H+ (BioCyc compound: C1).

Description: Ferroheme b or heme B (also known as protoheme IX) is the most abundant heme in nature. Pseudomonas aeruginosa is known to produce 4 different hemes: protoheme IX (heme B), heme C, heme D, and siroheme. A heme or haem is a prosthetic group that consists of an iron atom contained in the center of a large heterocyclic organic ring called a porphyrin. Not all porphyrins contain iron, but a substantial fraction of porphyrin-containing metalloproteins have heme as their prosthetic subunit; these are known as hemoproteins. Generally, heme B is attached to the surrounding protein matrix (known as the apoprotein) through a single coordination bond between the heme iron and an amino-acid side-chain. When oxygen is bound the iron becomes hexacoordinated. Since the iron in heme B containing proteins is bound to the four nitrogens of the porphyrin (forming a plane) and a single electron donating atom of the protein, the iron is often in a pentacoordinate state.

Description: FMNH2-dependent alkanesulfonate monooxygenase (gene name: ssuD) is an enzyme which catalyses the reaction 3-(N-morpholino)propanesulfonate + FMNH2 + oxygen ??3-(N-morpholino)propanal + sulfite + FMN + H2O + 2 H+ (BioCyc compound: CPD0-1958).

Description: Ethanesulfonate is a member of the chemical class known as Depsipeptides. These are natural or synthetic compounds having sequences of amino and hydroxy carboxylic acid residues (usually -amino and -hydroxy acids), commonly but not necessarily regularly alternating. It is also called Coenzyme M. Coenzyme M is a coenzyme required for methyl-transfer reactions in the metabolism of methanogens. The coenzyme is an anion with the formula HSCH2CH2SO_3. It is named 2-mercaptoethanesulfonate and abbreviated HS
