A deaminase specific for 4-aminopyrimidine nucleosides has been found in rye grass. Lolium perenne. The pH optimum, temperature stability, Km values and specificity was determined.A new and more accurate method for following the course of deamination is reported. This method depends on the shift in maximum absorbance wavelength of the mixture containing the 4-aminopyrimidine nucleoside and its deaminated product.
