Enzyme Information
| 1.1.1.41 |
Isocitrate dehydrogenase (NAD(+)).
based on mapping to UniProt P28834
Isocitrate + NAD(+) = 2-oxoglutarate + CO(2) + NADH.
-!- Unlike EC 1.1.1.42, oxalosuccinate cannot be used as a substrate. -!- In eukaryotes, isocitrate dehydrogenase exists in two forms: an NAD(+)-linked enzyme found only in mitochondria and displaying allosteric properties, and a non-allosteric, NADP(+)-linked enzyme that is found in both mitochondria and cytoplasm. -!- The enzyme from some species can also use NADP(+) but much more slowly.
