Protein attributes

Sequence length	447 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Catalyzes the conversion of glucosamine-6-phosphate to glucosamine-1-phosphate. Also catalyzes the isomerization of glucose-1-phosphate to glucose-6-phosphate, but at a 5-fold lower rate. Ref.2
Catalytic activity	Alpha-D-glucosamine 1-phosphate = D-glucosamine 6-phosphate. Ref.2
Cofactor	Binds 1 magnesium ion per subunit. Ref.2
Subunit structure	Monomer. Also forms large aggregates. Ref.2
Post-translational modification	Activated by phosphorylation. Glucose-1,6-bisphosphate or fructose-1,6-bisphosphate can activate the enzyme in vitro. However, since glucose-1,6-bisphosphate is not believed to form in methanogens, the physiologically relevant activator might be a serine kinase protein. HAMAP MF_01554
Sequence similarities	Belongs to the phosphohexose mutase family.
