Abstract
A new neutral endopeptidase having the properties of prolyl endopeptidase was detected in bovine lenses. The enzyme hydrolyzed the prolyl bond in the newly-developed fluorogenic substrate, t-butyloxycarbonyl-Arg-Pro-2-NNap, optimally at pH 8 and 37 degrees. The Km value was estimated to be 0.033 mM. An approximately 4-fold purification was achieved. DFP completely inhibited the hydrolysis of Boc-Arg-Pro-2-NNap by the endopeptidase.
