Functioni

Hydrolyzes mannosyl-3-phosphoglycerate (MPG) to form the osmolyte mannosylglycerate (MG). The enzyme is absolutely specific for MPG.1 Publication

Catalytic activityi

2-O-(alpha-D-mannosyl)-3-phosphoglycerate + H2O = 2-O-(alpha-D-mannosyl)-D-glycerate + phosphate.UniRule annotation1 Publication

Pathwayi: 2-(alpha-D-mannosyl)-D-glycerate biosynthesis

This protein is involved in step 2 of the subpathway that synthesizes 2-(alpha-D-mannosyl)-D-glycerate from GDP-alpha-D-mannose (MPG route).UniRule annotation
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Mannosyl-3-phosphoglycerate synthase (mngA)
  2. Mannosyl-3-phosphoglycerate phosphatase (mngB)
This subpathway is part of the pathway 2-(alpha-D-mannosyl)-D-glycerate biosynthesis, which is itself part of Carbohydrate biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes 2-(alpha-D-mannosyl)-D-glycerate from GDP-alpha-D-mannose (MPG route), the pathway 2-(alpha-D-mannosyl)-D-glycerate biosynthesis and in Carbohydrate biosynthesis.

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.
