CC -!- FUNCTION: Catalyzes the hydrolysis of fructose 1,6-bisphosphate (Fru
CC 1,6-P2) and sedoheptulose 1,7-bisphosphate (Sed 1,7-P2) to fructose 6-
CC phosphate and sedoheptulose 7-phosphate, respectively. {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=beta-D-fructose 1,6-bisphosphate + H2O = beta-D-fructose 6-
CC phosphate + phosphate; Xref=Rhea:RHEA:11064, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:32966, ChEBI:CHEBI:43474, ChEBI:CHEBI:57634; EC=3.1.3.11;
CC -!- CATALYTIC ACTIVITY:
CC Reaction=D-sedoheptulose 1,7-bisphosphate + H2O = D-sedoheptulose 7-
CC phosphate + phosphate; Xref=Rhea:RHEA:17461, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:57483, ChEBI:CHEBI:58335; EC=3.1.3.37;
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence={ECO:0000250};
CC -!- PATHWAY: Carbohydrate biosynthesis; Calvin cycle.
CC -!- SUBUNIT: Homotetramer. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the FBPase class 2 family. {ECO:0000305}.
