ABSTRACT
The beta-glucosidase of a root parasitic angiosperm, Orobanche minor Sm., was purified and characterized. The optimum pH and temperature for activity of the enzyme were 5.0 and 50 degrees C. The beta-glucosidase was stable at up to 50 degrees C at pH 4.0-10.0. The M(r) was estimated to be 33 kD by SDS-PAGE. The enzyme hydrolyzed p-nitrophenyl-beta-D-glucopyranoside and salicin, but not the cell wall of O. minor or cellohexaose.
