产品内容
本酶催化的反应为(1) A Protopanaxadiol-Type Ginsenoside With Two Glucosyl Residues At Position 3 + H2O = A Protopanaxadiol-Type Ginsenoside With One Glucosyl Residue At Position 3 + D-Glucopyranose;;
(2) A Protopanaxadiol-Type Ginsenoside With One Glucosyl Residue At Position 3 + H2O = A Protopanaxadiol-Type Ginsenoside With No Glycosidic Modifications At Position 3 + D-Glucopyranose;;(3) A Protopanaxadiol-Type Ginsenoside With Two Glycosyl Residues At Position 20 + H2O = A Protopanaxadiol-Type Ginsenoside With A Single Glucosyl Residue At Position 20 + A Monosaccharide，系统名称为Ginsenoside Glucohydrolase，I型人参皂苷酶被 Mg2+ 或 Ca2+ 轻微激活 [1]。该酶水解原人参二醇型人参皂苷的3-O-β-D-(1->2)-糖苷键、3-O-β-D-葡糖吡喃糖基键和20-O-β-D-(1->6)-糖苷键。它通常在20位留下单个葡萄糖基残基，在3位留有一个或不留葡萄糖基残基。以两位点均被糖基化的人参皂苷（如人参皂苷Rb1、Rb2、Rb3、Rc或Rd）为起始，最常见的产物是人参皂苷F2和人参皂苷C-K，并伴有少量人参皂苷Rh2。
