摘要:

The non-covalent immobilization of β-glucuronidase enzyme obtained from Rhizopus oryzae was carried outby entrapment in natural fiber (papaya and coconut).The bioconversion capability of immobilized enzyme was analyzed based on conversion ofglycyrrhizin to 18β-glycyrrhetinic acid under different conditions. The hydrolytic activity of the β-glucuronidase enzyme was highly depended on the microbial source and matrix, in which enzyme was immobilized. R. oryzae β-glucuronidase immobilized in papaya fibers produced the highest GA content (13.170 µg/mL) at 10 h of reaction. However R. oryzae β-glucuronidase immobilized in coconut fibers produced the highest GA content (21.425 µg/mL) at 15 h of reaction. Online Molinspiration software was used to predict drug like molecular properties of the 18β-glycyrrhetinic acid, and software suggested that the compounds had potential of becoming the orally active molecules. Therefore, in silico studies were conducted on proposed 18β-glycyrrhetinic acid to select the best possible drug candidates based on drug properties and bioactivity score of the compounds.
