CC -!- FUNCTION: Pyruvate carboxylase catalyzes a 2-step reaction, involving
CC the ATP-dependent carboxylation of the covalently attached biotin in
CC the first step and the transfer of the carboxyl group to pyruvate in
CC the second.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + hydrogencarbonate + pyruvate = ADP + H(+) + oxaloacetate
CC + phosphate; Xref=Rhea:RHEA:20844, ChEBI:CHEBI:15361,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:16452, ChEBI:CHEBI:17544,
CC ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=6.4.1.1;
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Name=Co(2+); Xref=ChEBI:CHEBI:48828;
CC -!- ACTIVITY REGULATION: Inhibited by ADP and alpha-ketoglutarate.
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC pH dependence:
CC Optimum pH is 8.;
CC Temperature dependence:
CC Optimum temperature is 60 degrees Celsius.;
CC -!- PATHWAY: Carbohydrate biosynthesis; gluconeogenesis.
CC -!- SUBUNIT: Heterooctamer of four A and four B subunits.
