- Purification and characterization of a tuliposide-converting enzyme from bulbs of tulipa gesneriana
-
An enzyme that catalyzes the stoichiometric conversion of 6-tuliposide into tulipalin was purified and characterized from bulbs of Tulipa gesneriana. The enzyme appeared to be a dimer, the relative molecular mass (Mr) of each subunit being 34,900; it had maximum activity and stability at neutral pH and moderate temperature. The enzyme preferentially acted on such glucose esters as 6-tuliposides, and to a lesser extent on /7-nitrophenylacetate.

Successful glycosynthase-mediated reactions have been performed on 6-O-benzyl-, 6-O-(4-nitrobenzyl)-, and 6-O-benzoyl-D-glucopyranose to give 1,2-β- and 1,3-β-D-glycosylated products; 4-O-benzyl-D-xylopyranose gave only a 1,2-β-glycosylated product. A rat
