Abstract

This superfamily represents a domain which consists of a 3-layer (alpha/beta/alpha) sandwich, and it is found in the enzymes 1D-myo-inositol 2-acetamido-2-deoxy-alpha-D-glucopyranoside deacetylase and N-acetylglucosaminyl-phosphatidylinositol de-N-acetylase, as well as in uncharacterised putative deacetylases.

1D-myo-inositol 2-acetamido-2-deoxy-alpha-D-glucopyranoside deacetylase ( 3.5.1.103 ) catalyzes the deacetylation of 1D-myo-inositol 2-acetamido-2-deoxy-alpha-D-glucopyranoside (GlcNAc-Ins) in the mycothiol biosynthesis pathway [ 1 ]. N-acetylglucosaminyl-phosphatidylinositol de-N-acetylase, ( 3.5.1.89 ) catalyses the second step in glycosylphosphatidylinositol (GPI) biosynthesis [ 2 ].


1. The crystal structure of 1-D-myo-inosityl 2-acetamido-2-deoxy-alpha-D-glucopyranoside deacetylase (MshB) from Mycobacterium tuberculosis reveals a zinc hydrolase with a lactate dehydrogenase fold. J. Biol. Chem. 278, 47166-70
2. Mammalian PIG-L and its yeast homologue Gpi12p are N-acetylglucosaminylphosphatidylinositol de-N-acetylases essential in glycosylphosphatidylinositol biosynthesis. Biochem. J. 339 ( Pt 1), 185-92
