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].
