The β-d-galactosidase from Bacillus circulans regioselectively galactosylates 1d-chiro-inositol and 1d-pinitol (1d-3-O-methyl-chiro-inositol) to give mono- and digalactosylated inositols in yields of up to 45%. The enzyme does not galactosylate 1l-chiro-inositol or 1l-quebrachitol (1l-2-O-methyl-chiro-inositol). This is the first report of enzymatic glycosylation of chiro-inositol and its derivatives.
