Abstract
1. Different porphobilinogen-deaminase (PBG-D) enzyme forms were found for D 27 and D 27/C6 (HEM R+) strains of Saccharomyces cerevisiae. 2. PBG-D was partially purified and chromatographed on Sephadex G-100 in either the presence or absence of a protease inhibitor. For D 27 only one active peak was observed while for D 27/C6 strain two active peaks were found. 3. A correlation between this differential behaviour and the presence of HEM R+ gene was looked for employing two segregants of one tetrad from D 27 and D 27/C6 mating.
