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         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: Algae contain three forms of GAPDH: two cytosolic forms
CC       which participate in glycolysis and one chloroplastic form which
CC       participates in photosynthesis. These three forms are encoded by
CC       distinct genes.
CC   -!- SIMILARITY: Belongs to the glyceraldehyde-3-phosphate dehydrogenase
CC       family. {ECO:0000305}.
