Protein attributes

Sequence length	464 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	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 O7 antigen.
Catalytic activity	GTP + alpha-D-mannose 1-phosphate = diphosphate + GDP-mannose.
Pathway	Nucleotide-sugar biosynthesis; GDP-alpha-D-mannose biosynthesis; GDP-alpha-D-mannose from alpha-D-mannose 1-phosphate (GTP route): step 1/1. Bacterial outer membrane biogenesis; LPS O-antigen biosynthesis.
Sequence similarities	Belongs to the mannose-6-phosphate isomerase type 2 family.
