Freesia protease (FP)-A has been found in regular freesia corms (Kaneda et al., Biosci. Biotechnol. Biochem. 61 (1997) 1554). New corms were generated from original corms that were kept for several months at 4°C. In this study, two proteases (FP-B a

The substrate specificity of a plant serine protease, cucumisin (EC 3.4.21.25), was studied by the use of synthetic oligopeptides and peptidyl- p NA substrates. Since P1′-Ser, Ala, and Gly substrates were hydrolyzed rapidly, cucumisin appears to pr

A protease has been purified from the sarcocarp of Benincasa hispida (Thunb.) Cogn. var. Ryukyu by two steps of chromatography. Its M r was estimated by SDS–PAGE to be about 67,000. The enzyme was strongly inhibited by diisopropyl fluorophosphate,
