A 50.4-fold purification of aminopeptidase is achieved by alcohol precipitation, DEAE-cellulose, CM-cellulose and finally Sephadex G-200 chromatography. On polyacrylamide gel electrophoresis of the purified enzyme after molecular sieving on Sephadex G-200, only one band was obtained, suggesting that the enzyme

Human pancreas, kidney, and liver alanine aminopeptidases have similar if not identical antigenic determinants even though these three isoenzymes have distinctly different electrophoretic mobilities. Single precipitin lines without spur formation were obtained for all three enzymes with antisera obtained from

The uptake of the peptide glycyl-L-leucine across the brush border of the rat small intestinal enterocyte was studied using everted rings. The transfer of leucine from the dipeptide into the enterocyte was greater than the glycine uptake from glycyl-L-leucine. This

A histochemical investigation was made of aminopeptidase activities using L-leucine-beta-naphthylamide and D, L-alanine-beta-naphthylamine as respective substrates in the rat's sensomotor cortex neurons during the period of ethanol withdrawal after a prolonged alcohol intoxication. Alcohol intoxication of the rat continued for

To elucidate the mechanisms involved in the increase in free amino acids during postmortem storage of meat, a novel aminopeptidase was purified from bovine skeletal muscle by ammonium sulfate fractionation and successive chromatographies such as DEAE-cellulose, Sephacryl S-200, Hydroxyapatite, Phenyl-Sepharose
