N-acetyl-1-D-myo-inositol-2-amino-2-deoxy-alpha-D-glucopyranoside deacetylase.
based on mapping to UniProt P9WJN3
1-O-(2-acetamido-2-deoxy-alpha-D-glucopyranosyl)-1D-myo-inositol + H(2)O = 1-O-(2-amino-2-deoxy-alpha-D-glucopyranosyl)-1D-myo-inositol + acetate.
-!- This enzyme is considered the key enzyme and rate limiting step in the mycothiol biosynthesis pathway. -!- In addition to acetylase activity, the enzyme possesses weak mycothiol conjugate amidase activity, and shares sequence similarity with mycothiol S-conjugate amidase. -!- Formerly EC 3.1.1.n1.
