Purification and Some Properties of an Esterase from Yeast

Noriko Toshimitsu; Hiroshi Hamada; Misao Kojima

Abstract An esterase was isolated and purified from bakers yeast by ammonium sulfate precipitation and column chromatographies on Sephacryl S-200, DEAE-Sephacel, chromatofocusing, and DEAE-Sephacel again. The molecular weight of the enzyme was approximately 84,000 on Sephadex G-100 and 40,000 by sodium dodecyl sulfate-poly-acrylamide gel electrophoresis, suggesting a dimer for the activity. This enzyme hydrolyzed short-chain naphthyl esters and p -nitrophenyl esters, and its activity was strongly inhibited by mercuric compounds. The esterase appeared to be an arylesterase (EC 3.1.1.2) and its optimum pH was 8.0 at 30°C.
