Studies on the immobilization of glucuronidase (Part 2). Cleavage of hardly soluble substrates in organic solvents.
Naturally occurring glucuronides and glucosides dissolved in organic solvents can be split with the help of beta-glucuronidase (EC 3.2.1.31) immobilized on controlled pore glass. To protect the enzyme against denaturation by the organic solvents and to promote hydrolytic cleavage of substrates, two methods were used: (a) Immobilization via crosslinking with aged glutaraldehyde in presence of bovine serum albumin; and (b) Adsorption of wet enzyme to the carrier in the presence of organic solvents.
