Strictosidine beta-D-glucosidase (E.C. 3.2.1.105) was partially purified from suspension cultured cells of Tabernaemontana divaricata. Three forms of different Mr were found, which all specifically catalysed the deglucosylation of strictosidine (Km 0.3-1 mM). Some enzyme characteristics resembled those described before for the Catharanthus roseus SG enzyme. Several products were shown to be formed after strictosidine hydrolysis, of which cathenamine 21-hydroxyajmalicine and iso-vallesiachotamine were identified.
