ID 6.4.1.7 DE 2-oxoglutarate carboxylase. AN carboxylating factor for ICDH. AN CFI. AN OGC. AN oxalosuccinate synthetase. CA 2-oxoglutarate + ATP + hydrogencarbonate = (S)-oxalosuccinate + ADP + CA H(+) + phosphate. CC -!- It was originally thought that this enzyme was a promoting factor for CC the carboxylation of 2-oxoglutarate by EC 1.1.1.41, but this has CC since been disproved. CC -!- The product of the reaction is unstable and is quickly converted into CC isocitrate by the action of EC 1.1.1.41. DR D3DJ41, 2OCL_HYDTT ; D3DJ42, 2OCS_HYDTT ; //
