CC -!- FUNCTION: Triosephosphate isomerase is an extremely efficient metabolic
CC enzyme that catalyzes the interconversion between dihydroxyacetone
CC phosphate (DHAP) and D-glyceraldehyde-3-phosphate (G3P) in glycolysis
CC and gluconeogenesis. {ECO:0000250|UniProtKB:P00939}.
CC -!- FUNCTION: It is also responsible for the non-negligible production of
CC methylglyoxal a reactive cytotoxic side-product that modifies and can
CC alter proteins, DNA and lipids. {ECO:0000250|UniProtKB:P00939}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=dihydroxyacetone phosphate = methylglyoxal + phosphate;
CC Xref=Rhea:RHEA:17937, ChEBI:CHEBI:17158, ChEBI:CHEBI:43474,
CC ChEBI:CHEBI:57642; EC=4.2.3.3;
CC Evidence={ECO:0000250|UniProtKB:P00939};
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|PROSITE-ProRule:PRU10127};
CC -!- PATHWAY: Carbohydrate degradation; glycolysis; D-glyceraldehyde 3-
CC phosphate from glycerone phosphate: step 1/1. {ECO:0000255|PROSITE-
CC ProRule:PRU10127}.
CC -!- PATHWAY: Carbohydrate biosynthesis; gluconeogenesis.
CC {ECO:0000255|PROSITE-ProRule:PRU10127}.
CC -!- SUBUNIT: Homodimer. {ECO:0000255|PROSITE-ProRule:PRU10127}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|PROSITE-ProRule:PRU10127}.
CC -!- SIMILARITY: Belongs to the triosephosphate isomerase family.
CC {ECO:0000305}.
