Purification and partial characterisation of NADP(+)-linked isocitrate dehydrogenase from rat liver cytosol
Abstract
NADP(+)-linked isocitrate dehydrogenase from rat liver cytosol was purified (approximately 135-fold) to apparent homogeneity in 27% yield. The purified enzyme has specific activity of 73 units.mg-1. The native enzyme showed an apparent M(r) of 94,000 by gel filtration and was composed of two identical subunits of M(r) 45,000 as judged by SDS/PAGE. In isoelectric focusing, a pI value of 5.7 was estimated for the enzyme.
