Peptidoglycan N acetylglucosamine deacetylase

Peptidoglycan-N-acetylglucosamine deacetylase (EC 3.5.1.104, HP310, PgdA, SpPgdA, BC1960, peptidoglycan deacetylase, N-acetylglucosamine deacetylase, peptidoglycan GlcNAc deacetylase, peptidoglycan N-acetylglucosamine deacetylase, PG N-deacetylase) is an enzyme with systematic name peptidoglycan-N-acetylglucosamine amidohydrolase. This enzyme catalyses the following chemical reaction

peptidoglycan-N-acetyl-D-glucosamine + H₂O ⇌ peptidoglycan-D-glucosamine + acetate

This enzyme contributes to virulence of Helicobacter pylori, Listeria monocytogenes and Streptococcus suis.
