The present invention relates to a process for enzymatically converting a furanoside substrate in a product of interest, comprising contacting said substrate with an enzyme in presence of an alcohol acceptor, wherein said enzyme is preferably Araf51, and wherein said product is preferably an alkyl furanoside. The present invention also relates to mutant Araf51 enzyme showing improved transglycosylation activity in comparison with the native wild-type (wt) Araf51 enzyme, and to a method for screening said mutants.
Araf51 with improved transglycosylation activities: one engineered biocatalyst for one specific acceptor
were selected on their ability to catalyze the transglycosylationreaction of p-nitrophenyl α-L-arabinofuranoside (pNP-Araf) used as a donor and various aliphatic alcohols as acceptors. This screening strategy underlined 5 interesting clones, each one corresponding to one acceptor. They appeared to be much more efficient in the transglycosylationreaction compared to the wild type enzyme whereas no self-condensation
