Functioni

Involved in xanthan production.By similarity

Catalytic activityi

D-mannose 6-phosphate = D-fructose 6-phosphate.
GTP + alpha-D-mannose 1-phosphate = diphosphate + GDP-mannose.

Pathwayi: GDP-alpha-D-mannose biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes GDP-alpha-D-mannose from alpha-D-mannose 1-phosphate (GTP route).
Proteins known to be involved in this subpathway in this organism are:
  1. Xanthan biosynthesis protein XanB (xanB)
This subpathway is part of the pathway GDP-alpha-D-mannose biosynthesis, which is itself part of Nucleotide-sugar biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes GDP-alpha-D-mannose from alpha-D-mannose 1-phosphate (GTP route), the pathway GDP-alpha-D-mannose biosynthesis and in Nucleotide-sugar biosynthesis.
