MshB, a zinc-based deacetylase, catalyses a step in the mycothiol biosynthetic pathway that involves the deacetylation of 1-O-(2-acetamido-2-deoxy-α-D-glucopyranosyl)-D-myo-inositol (GlcNAc-Ins), via cleavage of an amide bond, to 1-O-(2-amino-2-deoxy-α-D-glucopyranosyl)-D-myo-inositol (GlcN-Ins) and acetate. In this study, MshB was expressed, purified and crystallized. A

Chaperonins are ubiquitous molecular chaperones with the subunit molecular mass of 60kDa. They exist as double-ring oligomers with central cavities. An ATP-dependent conformational change of the cavity induces the folding of an unfolded protein that is captured in the cavity.
