Isolation and partial characterization of a protease from Cucurbita ficifolia

Abstract
A protease from the pulp of Cucurbita ficifolia was purified. Its molecular mass was estimated to be about 60 kDa. Its maximum activity is in the alkaline region against azocollagen as substrate. The enzyme is inhibited by phenylmethylsulphonyl fluoride but not by EDTA and iodoacetic acid.
