P. Christakopoulos et al., ENZYMATIC-SYNTHESIS OF TRISACCHARIDES AND ALKYL BETA-D-GLUCOSIDES BY THE TRANSGLYCOSYLATION REACTION OF BETA-GLUCOSIDASE FROM FUSARIUM-OXYSPORUM, International journal of biological macromolecules, 16(6), 1994, pp. 331-334
Purified beta-glucosidase from Fusarium oxysporum catalyses hydrolysis
and transglycosylation reactions. By utilizing the transglycosylation
reaction, trisaccharides and alkyl beta-D-glucosides were synthesized
under optimal conditions in the presence of various disaccharides and
alcohols. The yields of trisaccharides and alkyl beta-D-glucosides we
re 22-37% and 10-33% of the total sugar, respectively. The enzyme reta
ined 70-80% of its original activity in the presence of 25% (w/v) meth
anol, ethanol and propanol. Thus, beta-glucosidase from F. oxysporum a
ppears to be an ideal enzyme for the synthesis of useful trisaccharide
s and alkyl beta-D-glucosides.
