RT "Fructose 1,6-bisphosphate aldolase/phosphatase may be an ancestral
RT gluconeogenic enzyme.";
RL Nature 464:1077-1081(2010).
CC -!- FUNCTION: Catalyzes two subsequent steps in gluconeogenesis: the aldol
CC condensation of dihydroxyacetone phosphate (DHAP) and glyceraldehyde-3-
CC phosphate (GA3P) to fructose-1,6-bisphosphate (FBP), and the
CC dephosphorylation of FBP to fructose-6-phosphate (F6P).
CC {ECO:0000269|PubMed:20348906}.
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 Evidence={ECO:0000269|PubMed:20348906};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=beta-D-fructose 1,6-bisphosphate = D-glyceraldehyde 3-
CC phosphate + dihydroxyacetone phosphate; Xref=Rhea:RHEA:14729,
CC ChEBI:CHEBI:32966, ChEBI:CHEBI:57642, ChEBI:CHEBI:59776; EC=4.1.2.13;
CC Evidence={ECO:0000269|PubMed:20348906};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000250|UniProtKB:F9VMT6};
CC -!- PATHWAY: Carbohydrate biosynthesis; gluconeogenesis.
CC {ECO:0000305|PubMed:20348906}.
CC -!- SUBUNIT: Homooctamer; dimer of tetramers.
CC {ECO:0000250|UniProtKB:F9VMT6}.
CC -!- DOMAIN: Consists of a single catalytic domain, but remodels its active-
CC site architecture via a large structural change to exhibit dual
CC activities. {ECO:0000250|UniProtKB:F9VMT6}.
CC -!- SIMILARITY: Belongs to the FBP aldolase/phosphatase family.
CC {ECO:0000255|HAMAP-Rule:MF_02067, ECO:0000305}.
