Application

DL-alanine β-naphthylamide (DLABN) has been used as a substrate to treat Listeria in the hydrolysis test to compare methods for the identification of Listeria species. It has been used as a substrate in the hydrolysis of DLABN to differentiate Listeria monocytogenes from other Listeria species.

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

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

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

The hydrolysis of DL-alanine-beta-naphthylamide and D-alanine-p-nitroanilide for identification of Listeria spp. has been studied with 227 cultures. All species of Listeria, except L. monocytogenes, hydrolyzed these substrates. The reactions were detected by simple chromogenic reactions and could substitute for the

The localization of exopeptidase activities was demonstrated histochemically (by simultaneous azo coupling) on the visceral endoderm of whole unfixed yolk sacs of rats (12.5-18.5 days of gestation). For comparison, the topochemistry of exopeptidases was studied by conventional section histochemistry of
