| Name: | N-Acetylmuramoyl-L-alanyl-D-glutamyl-L-lysyl-D-alanyl-D-alanine-diphosphoundecaprenyl-N-acetylglucosamine |
|---|
| Description | N-acetylmuramoyl-L-alanyl-D-glutamyl-L-lysyl-D-alanyl-D-alanine-diphosphoundecaprenyl-N-acetylglucosamine is an intermediate in peptidoglycan synthesis. It is a substrate for the enzyme undecaprenyldiphospho-muramoylpentapeptide beta-N-acetylglucosaminyltransferase (murG). Peptidoglycan can be described as a fisherman's net that encloses bacteria. The mesh of the net is made of two segments of parallel, somewhat inextensible glycan threads, held together by two small elastic peptide crosslinks allowing the net to expand or shrink. The glycan moiety of the peptidoglycan is very uniform among all bacteria, and is made up of alternating β-1,4-linked N-acetylglucosamine and N-acetyl muramate residues, with an average chain lengthof 10 to 65 disaccharide units (depending on the organism). The peptidoglycan synthesis pathway starts in 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-α-D-glucosamine, yielding the complete monomeric unit a lipid II, also known as lipid II. This final lipid intermediate is transferred by an as yet unknown mechanism 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. Peptide crosslinks form between different parts of the peptides depending on the organism. For example, in Mycobacteria and in E. coli most links form between the carboxyl group of the penultimate D-alanine (residue 4) of one peptide to the amino group at the D-center of meso-diaminopimelate (residue 3) of an adjacent peptide of a second glycan chain (as in E. coli). The crosslinking reaction is catalyzed by transpeptidases and involves the cleavage of the D-alanyl-D-alanine bond of the donor peptide, providing the energy to drive the reaction. As a result, the peptides in the peptidoglycan polymers are one or two amino acids shorter than the peptides in the monomers. |
