~~ ~Subcellular localization of the starch-degrading enzymes in Vicia faba leaves was achieved by an electrophoretic transfer method through a starch-containing gel (SCC) and enzyme activity measurements. Total amylolytic and phosphorolytic activities were found predominantly in the extrachloroplastic fraction, whereas the debranching enzymes showed homogenous distribution between stromal and extrachloroplastic fractions. Staining of end products in the SCC revealed two isoforms of a-amylase (EC
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
