CC   -!- FUNCTION: Involved in the gluconeogenesis. Catalyzes stereospecifically
CC       the conversion of dihydroxyacetone phosphate (DHAP) to D-
CC       glyceraldehyde-3-phosphate (G3P). {ECO:0000255|HAMAP-Rule:MF_00147}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=D-glyceraldehyde 3-phosphate = dihydroxyacetone phosphate;
CC         Xref=Rhea:RHEA:18585, ChEBI:CHEBI:57642, ChEBI:CHEBI:59776;
CC         EC=5.3.1.1; Evidence={ECO:0000255|HAMAP-Rule:MF_00147};
CC   -!- PATHWAY: Carbohydrate biosynthesis; gluconeogenesis.
CC       {ECO:0000255|HAMAP-Rule:MF_00147}.
CC   -!- PATHWAY: Carbohydrate degradation; glycolysis; D-glyceraldehyde 3-
CC       phosphate from glycerone phosphate: step 1/1. {ECO:0000255|HAMAP-
CC       Rule:MF_00147}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00147}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00147}.
CC   -!- SIMILARITY: Belongs to the triosephosphate isomerase family.
CC       {ECO:0000255|HAMAP-Rule:MF_00147}.
