Kinetic analysis of NAD(+)-isocitrate dehydrogenase with altered isocitrate binding sites: contribution of IDH1 and IDH2 subunits to regulation and catalysis.

Biochemistry - 14 Sept 1993

Cupp J R, McAlister-Henn L

Abstract excerpt

NAD(+)-dependent isocitrate dehydrogenase from Saccharomyces cerevisiae is an allosterically regulated enzyme that exists as an octamer composed of two nonidentical subunits, designated IDH1 and IDH2. To determine the contribution of each subunit to regulation and catalysis, a conserved serine residue at the proposed active site of each subunit was mutated to alanine. This mutation in IDH1 resulted in a 6-fold...
