RT "Increased expression of a gene coding for NAD:glyceraldehyde-3-phosphate
RT dehydrogenase during the transition from C3 photosynthesis to crassulacean
RT acid metabolism in Mesembryanthemum crystallinum.";
RL J. Biol. Chem. 265:3497-3502(1990).
CC -!- FUNCTION: Key enzyme in glycolysis that catalyzes the first step of the
CC pathway by converting D-glyceraldehyde 3-phosphate (G3P) into 3-
CC phospho-D-glyceroyl phosphate. Essential for the maintenance of
CC cellular ATP levels and carbohydrate metabolism (By similarity).
CC {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=D-glyceraldehyde 3-phosphate + NAD(+) + phosphate = (2R)-3-
CC phospho-glyceroyl phosphate + H(+) + NADH; Xref=Rhea:RHEA:10300,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:43474, ChEBI:CHEBI:57540,
CC ChEBI:CHEBI:57604, ChEBI:CHEBI:57945, ChEBI:CHEBI:59776; EC=1.2.1.12;
CC Evidence={ECO:0000255|PROSITE-ProRule:PRU10009};
CC -!- PATHWAY: Carbohydrate degradation; glycolysis; pyruvate from D-
CC glyceraldehyde 3-phosphate: step 1/5.
CC -!- SUBUNIT: Homotetramer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC -!- MISCELLANEOUS: Plants contain two types of GAPDH: cytosolic forms which
CC participate in glycolysis and chloroplast forms which participate in
CC photosynthesis. All the forms are encoded by distinct genes.
CC -!- SIMILARITY: Belongs to the glyceraldehyde-3-phosphate dehydrogenase
CC family. {ECO:0000305}.
