Protein attributes

Sequence length471 AA.
Sequence statusComplete.
Protein existenceEvidence at transcript level

General annotation (Comments)

Function

Synthesis and degradation of fructose 2,6-bisphosphate.

Catalytic activity

Beta-D-fructose 2,6-bisphosphate + H2O = D-fructose 6-phosphate + phosphate.

ATP + D-fructose 6-phosphate = ADP + beta-D-fructose 2,6-bisphosphate.

Enzyme regulation

Phosphorylation results in inhibition of the kinase activity By similarity.

Subunit structure

Homodimer By similarity.

Tissue specificity

Liver By similarity.

Sequence similarities

In the C-terminal section; belongs to the phosphoglycerate mutase family.
