title: Effect of gluco-monosaccharides and different conditions on digestion of hyaluronan by testicular hyaluronidase.
abstract: The changes of molecular size of hyaluronan during enzymatic reaction of bovine testicular hyaluronidase at different conditions are monitored by size exclusion high performance liquid chromatography. The effect of glucuronate, galacturonate, glucosamines and pyridoxin as potential inhibitors of hydrolysis is evaluated. The most effective of all tested inhibitors was the presence of glucuronate which not only inhibited the hydrolysis, but also initiated enzymatic reconstruction by transglycosylation reaction at pH 7.0 and absence of any buffer or salt. That effect was not found in the presence of a salt or with any other of the compounds tested.
