Description: D-glycero-D-manno-heptose in which the hydrogen of the primary hydroxy group is substituted by a dihydrogen phosphate group

Description: 5-Phospho-ribosylglycinamide is an intermediate in puriine biosynthesis. It is a substrate for the enzyme Phosphoribosylglycinamide synthetase (EC:6.3.4.13) (GARS) which catalyses the second step in the de novo biosynthesis of purine. The reaction catalysed by phosphoribosylglycinamide synthetase is the ATP-dependent addition of 5-phosphoribosylamine to glycine to form 5'-phosphoribosylglycinamide.

Description: N-Acetyl-L-methionine is an acylated methionine derivative. The N-terminal methionine is often released from peptides and proteins in Pseudomonas aeruginosa via methionine aminopeptidase. The free methionine can be acetylated by the enzyme YncA or N acyltransferase in a reaction using a CoA thioester as cofactor.

Description: Tricarboxylate anion of (2S,3R)-3-hydroxybutane-1,2,3-tricarboxylic acid

Description: (2R,3S)-2-Hydroxybutane-1,2,3-tricarboxylate is an intermediate in methylcitrate metabolism. It is involved in the reaction propinoyl-CoA + H2O + oxaloacetate = (2R,3S)-2-hydroxybutane-1,2,3-tricarboxylate + CoA which is mediated by the enzyme: 2-methylcitrate synthase.

Description: 2-((2R,5Z)-2-Carboxy-4-methylthiazol-5(2H)-ylidene)ethyl phosphate is an intermediate involved in thiamine diphosphate biosynthesis. Thiamine diphosphate, also known as vitamin B1, is known to play a fundamental role in energy metabolism. It is an essential cofactor for a variety of enzymes such as transketolase, pyruvate dehydrogenase, pyruvate decarboxylase, and alpha-ketoglutarate dehydrogenase. Thiamine is synthesized de novo by microorganisms, plants and some lower eukaryotes (e.g. Plasmodium), but not by higher eukaryotes, which must obtain it through their diet.

Description: Quinone is also called 1,4-benzoquinone or cyclohexadienedione. Quinones are oxidized derivatives of aromatic compounds and are often readily made from reactive aromatic compounds with electron-donating substituents such as phenols and catechols, which increase the nucleophilicity of the ring and contributes to the large redox potential needed to break aromaticity. Derivatives of quinones are common constituents of biologically relevant molecules. Some serve as electron acceptors in electron transport chains such as those in photosynthesis (plastoquinone, phylloquinone), and aerobic respiration (ubiquinone).

Description: A D-glucopyranose 6-phosphate where α-D-glucose is the sugar component

Description: (2-N,3-O-bis(3-hydroxytetradecanoyl)-4-O-phosphono-beta-D-glucosaminyl)-(1->6)-(2-N,3-O-bis(3-hydroxytetradecanoyl)-beta-D-glucosaminyl phosphate) is a substrate for tetraacyldisaccharide 4'-kinase. This is an enzyme that phosphorylates the 4'-position of a tetraacyldisaccharide 1-phosphate precursor (DS-1-P) of lipopolysaccharide lipid A. This lipid which is part of LPS, forms the outer membranes of Gram-negative bacteria. This enzyme catalyzes the chemical reaction: ATP + [2-N,3-O-bis(3-hydroxytetradecanoyl)-beta-D-glucosaminyl]-(1->6)-[2- N,3-O-bis(3-hydroxytetradecanoyl)-beta-D-glucosaminyl phosphate] <=> ADP + [2-N,3-O-bis(3-hydroxytetradecanoyl)-4-O-phosphono-beta-D-glucosaminyl]-(1->6)-[2-N,3-O-bis(3-hydroxytetradecanoyl)-beta-D- glucosaminyl phosphate]

Description: 2,3-bis(3-Hydroxytetradecanoyl)-D-glucosaminyl-1,6-beta-D-2,3-bis(3-hydroxytetradecanoyl)-beta-D-glucosaminyl 1-phosphate is an intermediate in LPS synthesis. It is a substrate for the protein tetraacyldisaccharide 4'-kinase which catalyzes the reaction: ATP + 2,3-bis(3-hydroxytetradecanoyl)-D-glucosaminyl-(beta-D-1,6-)-2,3-bis(3-hydroxytetradecanoyl)-D-glucosaminyl beta-phosphate = ADP + 2,3,2',3'-tetrakis(3-hydroxytetradecanoyl)-D-glucosaminyl-1,6-beta-D-glucosamine 1,4'-bisphosphate
