Abstract
The aminopeptidase activity in the brain which converts vasopressin into centrally active metabolites, was quantitated on basis of the release of 3H-Phe from the substate [3H-Phe3]vasopressin and separation by hydrophobic interaction chromatography on mini-columns. After subcellular fractionation of whole rat brain homogenates the highest specific activity of the peptidase was
