Common NameN-Acetylmuramic acid 6-phosphate
DescriptionN-acetylmuramic acid 6-phosphate is a member of the chemical class known as Sugar Acids and Derivatives. These are compounds containing a saccharide unit which bears a carboxylic acid group. The enzyme MurQ is an N-acetylmuramic acid 6-phosphate (MurNAc 6-phosphate) hydrolase (or etherase) that hydrolyzes the lactyl side chain from MurNAc 6-phosphate and generates GlcNAc 6-phosphate. (PMID 18837509 ). It is a key component of peptidoglycan synthesis. The peptidoglycan synthesis pathway starts at the cytoplasm, where in six steps the peptidoglycan precursor a UDP-N-acetylmuramoyl-pentapeptide is synthesized. This precursor is then attached to the memberane acceptor all-trans-undecaprenyl phosphate, generating a N-acetylmuramoyl-pentapeptide-diphosphoundecaprenol, also known as lipid I. Another transferase then adds UDP-N-acetyl-alpha-D-glucosamine, yielding the complete monomeric unit a lipid , also known as lipid . This final lipid intermediate is transferred through the membrane. The peptidoglycan monomers are then polymerized on the outside surface by glycosyltransferases, which form the linear glycan chains, and transpeptidases, which catalyze the formation of peptide crosslinks.
