Formation of local structure and overall chain dimensions in the 124-residue, four-disulfide protein bovine pancreatic ribonuclease A (RNase A) under conditions favoring either the native or partially folded states have been studied by nonradiative excitation energy transfer measurements. Three RNase

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
