Protein

1,6-anhydro-N-acetylmuramyl-L-alanine amidase AmpD

Gene

ampD

Organism
Escherichia coli (strain K12)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at transcript leveli

Functioni

Involved in both cell wall peptidoglycans recycling and beta-lactamase induction. Specifically cleaves the amide bond between the lactyl group of N-acetylmuramic acid and the alpha-amino group of the L-alanine in degradation products containing an anhydro N-acetylmuramyl moiety (By similarity).By similarity

Catalytic activityi

Hydrolyzes the link between N-acetylmuramoyl residues and L-amino acid residues in certain cell-wall glycopeptides.

Cofactori

Zinc; required for amidase activity.By similarity

Expressioni

Inductioni

Inactivation of AmpD results in AmpR-dependent hyperinduction and AmpD affects beta-lactam susceptibility in the absence of cloned C.freundii amp genes suggesting a linkage between AmpD and peptidoglycan synthesis.
