Common NameUndecaprenyl-diphospho-N-acetylmuramoyl-(N-acetylglucosamine)-L-alanyl-D-glutaminyl-meso-2,6-diaminopimeloyl-D-alanyl-D-alanine
DescriptionUndecaprenyl-diphospho-n-acetylmuramoyl-(n-acetylglucosamine)-l-alanyl-d-glutaminyl-meso-2,6-diaminopimeloyl-d-alanyl-d-alanine is a peptide. 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-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.
