IDP2

isocitrate dehydrogenase (NADP(+)) IDP2, L000002737, YLR174W
Cytosolic NADP-specific isocitrate dehydrogenase; catalyzes oxidation of isocitrate to alpha-ketoglutarate; levels are elevated during growth on non-fermentable carbon sources and reduced during growth on glucose; IDP2 has a paralog, IDP3, that arose from the whole genome duplication

Dosage Rescue

A genetic interaction is inferred when over expression or increased dosage of one gene rescues the lethality or growth defect of a strain that is mutated or deleted for another gene.

Kinetic properties and metabolic contributions of yeast mitochondrial and cytosolic NADP+-specific isocitrate dehydrogenases.

Contreras-Shannon V, Lin AP, McCammon MT, McAlister-Henn L

To compare kinetic properties of homologous isozymes of NADP+-specific isocitrate dehydrogenase, histidine-tagged forms of yeast mitochondrial (IDP1) and cytosolic (IDP2) enzymes were expressed and purified. The isozymes were found to share similar apparent affinities for cofactors. However, with respect to isocitrate, IDP1 had an apparent Km value approximately 7-fold lower than that of IDP2, whereas, with respect to alpha-ketoglutarate, IDP2 ... [more]
