'''Mur ligase''' are a set of four Mur ubiquitin ligase enzymes: MurC, MurD, MurE, MurF which catalyze the addition of a short polypeptide to UDP-D-acetylmuramic acid in the process of bacterial cell wall buildup from peptidoglycans<ref>PMID:23555903</ref>. All four enzymes are topologically similar. | '''Mur ligase''' are a set of four Mur ubiquitin ligase enzymes: MurC, MurD, MurE, MurF which catalyze the addition of a short polypeptide to UDP-D-acetylmuramic acid in the process of bacterial cell wall buildup from peptidoglycans<ref>PMID:23555903</ref>.
