The reabsorption of filtered di- and tripeptides as well as certain peptide mimetics from the tubular lumen into renal epithelial cells is mediated by an H+-coupled high-affinity transport process. Here we demonstrate for the first time H+-coupled uptake of dipeptides

l. Recently two genes have been identified by expression cloning that encode mammalian epithelial peptide transporters capable of translocating di- and tripeptides and selected peptidomimetics by stereoselective and rheogenic substrate-H+ cotransport. PepT1 from rabbit or human small intestine induces a
The purpose of present study was to determine whether peptidase activity affects the release of substance P (SP) and calcitonin gene-related peptide (CGRP) from spinal cord slices. When slices were exposed to various inhibitors of endopeptidase 24.11, the resting and

The methylotrophic yeast Pichia pastoris was used for heterologous expression of the rabbit intestinal peptide transporter PepT1 and its functional characterization. PepT1 mediates the electrogenic transmembrane transport of di- and tripeptides and peptido-mimetics such as beta-lactam antibiotics and ACE-inhibitors. Functional
This study was initiated to develop inhibitors of the intestinal H(+)/peptide symporter. We provide evidence that the dipeptide derivative Lys[Z(NO(2))]-Pro is an effective competitive inhibitor of mammalian PEPT1 with an apparent binding affinity of 5-10 microM. Characterization of the interaction
