N-acetyl-1-D-myo-inositol-2-amino-2-deoxy-alpha-D-glucopyranoside deacetylase (EC 3.5.1.103, MshB) is an enzyme with systematic name 1-(2-acetamido-2-deoxy-alpha-D-glucopyranosyl)-1D-myo-inositol acetylhydrolase.[1][2][3] This enzyme catalyses the following chemical reaction
- 1-(2-acetamido-2-deoxy-alpha-D-glucopyranosyl)-1D-myo-inositol + H2O 1-(2-amino-2-deoxy-alpha-D-glucopyranoside)-1D-myo-inositol + acetate
This enzyme mediates the rate limiting step in the mycothiol biosynthesis pathway.
