Protein attributes

Sequence length	338 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level

General annotation (Comments)

Catalytic activity	D-fructose 1,6-bisphosphate + H2O = D-fructose 6-phosphate + phosphate.
Cofactor	Binds 3 magnesium ions per subunit By similarity.
Enzyme regulation	Subject to complex allosteric regulation. The enzyme can assume an active R-state, or an inactive T-state. Intermediate conformations may exist. AMP acts as allosteric inhibitor. AMP binding affects the turnover of bound substrate and not the affinity for substrate. Fructose-2,6-biphosphate acts as competitive inhibitor. Fructose-2,6-biphosphate and AMP have synergistic effects By similarity.
Pathway	Carbohydrate biosynthesis; gluconeogenesis.
Subunit structure	Homotetramer By similarity.
Sequence similarities	Belongs to the FBPase class 1 family.
