Name: UDP-N-Acetylmuramyl-L-Ala
Description:UDP-n-acetylmuramyl-L-Ala is a precursor to peptidoglycan synthesis. UDP-N-acetylmuramoyl-L-alanine (UDP-MurNAc-L-Ala), which is the nucleotide substrate of the D-glutamic-acid-adding enzyme (the murD gene product) catalyzes key steps in the pathway for peptidoglycan synthesis. (PMID 8098327) MurD (UDP-N-acetylmuramoyl-L-alanine:D-glutamate ligase) is the second enzyme in the series of Mur ligases, and it catalyzes the addition of D-glutamic acid (D-Glu) to the cytoplasmic intermediate UDP-N-acetylmuramoyl-L-alanine (UMA). (PMID 19007109) 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-D-glucosamine, yielding the complete monomeric unit a lipid II, also known as lipid II. 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.
