Effects of pH (▴) and temperature (■) on X-PDP activity from L. sakei using Gly-Pro-AMC as substrate. The activities at optimal pH and temperature were given a value of 100%, which corresponded to 0.011 and 0.012 U (μmol h−1), respectively. The degree of purification of the enzyme preparation used was of 716.6-fold.
