Abstract
Aqueous extracts of peas ( Pisum rativum L.) and green beans ( Phaseolus vulgaris L.) were subjected to zone electrophoresis on polyacrylamide-gel. α-Naphthyl acetate and propionate were hydrolysed in preference to α-naphthyl butyrate and naphthol AS acetate by most of the vegetable esterases. At least 14 beans of esterase activity in green beans were separated into three groups. Components of the two faster migrating groups demonstrated similar substrate and inhibitor specificities and, hence, appeared to be isozymes, whereas components of the slowest migrating group differed in substrate specificity. Results with pea esterases revealed the presence of seven distinct esterase bands. The six slower migrating bands behaved as isozymes band 7, wich may contain four components, was more resistant to organophosphorus inhibitors and shape differences in substrate specificities from bands 1–6.
