Protein

Phosphomannomutase

Gene

manB

Organism
Escherichia coli
Status
Reviewed - Annotation score: 4 out of 5- Protein inferred from homologyi

Functioni

Involved in GDP-mannose biosynthesis which serves as the activated sugar nucleotide precursor for mannose residues in cell surface polysaccharides. This enzyme participates in synthesis of the LPS O9 antigen.

Catalytic activityi

Alpha-D-mannose 1-phosphate = D-mannose 6-phosphate.

Cofactori

Binds 1 magnesium ion per subunit.By similarity
