Abstract
Aminopeptidase A (l-α-aspartyl(l-α-glutamyl)-peptide hydrolase, EC 3.4.11.7) was found in human placenta, partially purified from it and briefly characterized in comparison with the placental leucine aminopeptidase. The aminopeptidase A could be separated from leucine aminopeptidase after trypsin digestion followed by Sephacryl S-300 chromatography. The angiotensinase (EC 3.4.99.3) activity of aminopeptidase A in human placenta was confirmed by a biological method.
