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.
β-葡萄糖苷酶从玫瑰‘浩君’花瓣中部分纯化得到。该酶对诸如2-苯乙基β-D-吡喃葡萄糖苷等β-D-吡喃葡萄糖苷具有高度特异性。在pH 6.0和35℃下观察到最佳活性。通过蓝色非变性聚丙烯酰胺凝胶电泳分析，该酶由两种蛋白质（160 kDa和155 kDa）组成，并基于液相色谱-串联质谱分析被归类为1类葡萄糖苷酶。
