Protein

D-inositol 3-phosphate glycosyltransferase

Gene

mshA

Organism
Salinispora tropica (strain ATCC BAA-916 / DSM 44818 / CNB-440)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Catalyzes the transfer of a N-acetyl-glucosamine moiety to 1D-myo-inositol 3-phosphate to produce 1D-myo-inositol 2-acetamido-2-deoxy-glucopyranoside 3-phosphate in the mycothiol biosynthesis pathway.UniRule annotation

Catalytic activityi

UDP-N-acetyl-D-glucosamine + 1D-myo-inositol 3-phosphate = UDP + 1-O-(2-acetamido-2-deoxy-alpha-D-glucopyranosyl)-1D-myo-inositol 3-phosphate.UniRule annotation

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
