Abstract

Isolation and purification of "malic-enzyme" NADP was done using fractionation by ammonium sulfate, anion-exchange chromatography on DEAE cellulose, gel-filtration through Sephadex G-200 and purification on DEAE Sephadex A-50. The isoenzyme isolated had a specific activity of 40-50 mkM/mg protein per min (approximately 80-fold purification) and contained negligible admixtures.
