✦ Synopsis

An inhibitor of $-D-glucosidase (E.C. 3.2.1.21) was found to be present in commercial yeast extract. The inhibitor was shown to be heat-labile, of low molecular weight, and unstable at acid pH. Inhibition was noncompetitive and apparently was not caused by proteinaceous material. Fractionation of the yeast extract was carried out on DEAE-Sepharose, to which the inhibitor did not bind.
