EC 3.5.1.104     
Accepted name: peptidoglycan-N-acetylglucosamine deacetylase
Reaction: peptidoglycan-N-acetyl-D-glucosamine + H2O = peptidoglycan-D-glucosamine + acetate
Other name(s): HP310; PgdA; SpPgdA; BC1960; peptidoglycan deacetylase; N-acetylglucosamine deacetylase; peptidoglycan GlcNAc deacetylase; peptidoglycan N-acetylglucosamine deacetylase; PG N-deacetylase
Systematic name: peptidoglycan-N-acetylglucosamine amidohydrolase
Comments: Modification of peptidoglycan by N-deacetylation is an important factor in virulence of Helicobacter pylori, Listeria monocytogenes and Streptococcus suis [4-6]. The enzyme from Streptococcus pneumoniae is a metalloenzyme using a His-His-Asp zinc-binding triad with a nearby aspartic acid and histidine acting as the catalytic base and acid, respectively [3].
