ginsenosidase type IV hydrolyzes the sugars linked to C-6 in the PPT-type ginsenosides. Ginsenosidase type IV enzymes are subdivided into types IV-i-1, IV-i-2, IV-i-3, and IV-ii. Ginsenosidase type IV-i-2 enzymes convert ginsenosides Re and Rg2 to ginsenosides Rg1 and Rh1, respectively, by hydrolyzing only the outer rhamnose linked to C-6 in the PPT-type ginsenosides with the hydrolysis pattern of E-2

ginsenosidase type IV hydrolyzes the sugars linked to C-6 in the PPT-type ginsenosides. Ginsenosidase type IV enzymes are subdivided into types IV-i-1, IV-i-2, IV-i-3, and IV-ii. Ginsenosidase type IV-i-1 enzymes convert ginsenoside Rf to Rh1 by the hydrolysis of only the outer glucose linked to C-20 and not the inner glucose linked to C-6 in the PPT-type ginsenosides with the hydrolysis pattern of E-1. This conversion has been conducted by beta-glycosidase from Aspergillus niger

ginsenosidase type IV hydrolyzes the sugars linked to C-6 in the PPT-type ginsenosides. Ginsenosidase type IV enzymes are subdivided into types IV-i-1, IV-i-2, IV-i-3, and IV-ii. Ginsenosidase type IV-ii enzymes convert ginsenosides Rg1 and Rh1, containing only the inner glucose without the outer sugar at C-6, are converted to ginsenosides F1 and aglycone protopanaxatriol (APPT), respectively, by hydrolyzing the inner glucose linked to C-6 but not the glucose linked to C-20 in the PPT-type ginsenosides with the hydrolysis pattern of F. Ginsenosidase type IV-ii enzymes also hydrolyze the outer glucose of ginsenoside Rf, which has the outer and inner glucose at C-6 with the hydrolysis pattern of E-1; the outer rhamnose of ginsenosides Re and Rg2, which have the outer rhamnose and inner glucose at C-6 with the hydrolysis attern of E-2, and the outer xylose of notoginsenosides R1 and R2, which contain the outer xylose and inner glucose at C-6 with the hydrolysis pattern of E-3
