Abstract

The title enzyme from Bacillus licheniformis has been shown to catalyse the effective autocondensation of β-laminaribiosyl fluoride, and lead to alternate 1, 3-1, 4-β-D- glucotetraose and-glucohexaose products. The transglycosylation using the same donor and methyl β-laminaribioside as acceptor leads to the methyl 4-O-β-laminaribiosyl-β- laminaribioside in 40% overall yield.
