Beta-glucosidase was partially purified from Rosa 'Hoh-Jun' petals. The enzyme was highly specific for such beta-D-glucopyranosides as 2-phenylethyl beta-D-glucopyranoside. The optimal activity was observed at pH 6.0 and 35 degrees C. The enzymes were composed with two proteins (160 and 155 kDa) by blue native-PAGE, and were classified in a family 1 glucosidase based on LC-MS/MS analyses.
