Bovine pancreatic RNase A catalyzing the hydrolysis of urea. Net absorbance at 340 nm was scanned after adding bovine pancreatic RNase A [6.7 μg protein (upper line) and 20 μg protein (lower line)] into the reaction mixture for urease activity assay. Data indicates a positive correlation between the amounts of RNase A added to the reaction mixture and the breakdown of urea. A very similar graph was obtained with pecan sap RNase A catalyzing the hydrolysis of urea.
