Glucosylation of methyl β-D-arabinofuranoside with 6'-chloro-6'-deoxysucrose and immobilized Protaminobacter rubrum.

Transglucosylation byProtaminobacter rubrum using 6'-chloro-6'-deoxysucrose (1) and methyl β-D-arabinofuranoside (2) as donor and acceptor, respectively, were examined. inhibition caused by 6-chloro-6-deoxy-D-fructose (4) was observed and could be greatly lightened in a borate buffer, where the yield of the disaccharide (3) increased by 1.35-fold.
