NOVEL ASSAYS FOR THE MEASUREMENT OF GLUCURONYL ESTERASE AND a-GLUCURONIDASE, TWO ENZYMES INVOLVED IN LIGNIN AND HEMICELLULOSE HYDROLYSIS

摘要

Following the successful development of enzyme-coupled colorimetric assays for the measurement of a range of endo-acting glycosyl hydrolases including endo-1,4-ss-glucanase [1], erdo-1,4-3-xylanase [2], our research activity has been focused on two additional classes of glycosyl hydrolases: namely glucuronoyl esterase (GE) and a-glucuronidase.
