The cyanogenic disaccharide glycoside, vicianin [mandelonitrile beta-vicianoside (6-O-alpha-L-arabinopyranosyl-beta-D-glucopyranoside)], is accumulated in seeds of Vicia angustifolia var. segetalis. Vicianin hydrolase (VH) catalyzes the hydrolysis of vicianin into mandelonitrile and a disaccharide vicianose. VH was purified from the seeds using DEAE-, CM- and Con A-Sepharose chromatography, and the molecular mass of the purified VH was estimated to be 56 kDa on SDS-PAGE. The N-terminal amino… CONTINUE READING
