Two glucosyltransferases were isolated from plant cell cultures of Catharanthus roseus and Nicotiana tabacum. The enzyme from C. roseus enantioselectively glucosylated (±)-secondary alcohols to give the glucosides of (R)-alcohols, while the glucosylation with that from N. tabacum gave preferentially the glucosides of (S)-alcohols.
Anomer selective formation of l-menthyl α-D-glucopyranoside by α- glucosidase-catalyzed reaction

l-Menthol was glucosylated by the α-glucosidase (EC 3.2.1.20) of Saccharomyces cerevisiae using maltose as glucosyl donor. When 50 mg of l- menthol and 1 M maltose in 10 mM citrate-phosphate buffer (pH 7.0) were incubated for 24 h at 30°C, a menthylglucoside was selectively obtained as a product. The molar conversion yield based on supplied menthol was 4.5%. The product was identified as l-menthyl α-D-glucopyranoside (α-MenG) by 13C- NMR analysis.
