Abstract excerpt
During a screen for respiration competent yeast mutants that were unable to grow with acetate as a carbon source, two idh2 cit1 double mutants were identified. These strains were defective in the catalytic subunit of the NAD(+)-dependent isocitrate dehydrogenase and citrate synthase of the tricarboxylic acid (TCA) cycle. The strains harboring the idh2 alleles from these strains had two unusual phenotypes. First,...
