peptidoglycan-N-acetyl-D-glucosamine + H2O | substrates: peptidoglycans digested by DL-endopeptidase, or by LD-endopeptidase, or by L-alanine amidase, the latter is a very poor substrate. Purified recombinant and truncated enzyme, expressed in Escherichia coli, deacetylates Bacillus subtilis peptidoglycan and its polymer, (-GlcNAc-MurNAc[-L-Ala-D-Glu]-)n. The enzyme deacetylates N-acetylmuramic acid not N-acetyl-D-glucosamine from the polymer. The enzyme PdaC is a unique enzyme exhibiting two different deacetylase activities. The enzyme works as a MurNAc deacetylase toward glycan strands containing L-Ala-D-Glu | Bacillus subtilis | peptidoglycan-D-glucosamine + acetate | - |
