Abstract
A serine endopeptidase (SEP) was found to be possibly involved in the degra dation of storage proteins in cotyledons of germinated Vigna mungo seeds. S EP activity was separated into two isoforms by CM-cellulose column chromato graphy. These forms, termed SEP-I and SEP-II, showed endopeptidase activiti es even at acidic pH, suggesting that SEPs are unique serine endopeptidases , since most serine proteases are optimum at neutral pH.
