Abstract

-Glucosidase has been purified from culture fluid and from lysed cells of NCIB 6346. The enzymes from these two sources were virtually identical in molecular weight as judged by SDS-PAGE (63000) and catalytic properties. The enzymes were unstable at high temperature and lost all activity after incubation at 60°C for 10 min. Of the substrates examined, isomaltose gave maximal activity, followed by maltotriose, -nitrophenyl --glucopyranoside, sucrose and maltose. With isomaltose or maltotriose as substrate, transglucosylation activity was evident.
