Abstract: Complementary RNA, derived from the intestine of the sea bass Dicentrarchus labrax and putatively coding for a pH-dependent oligopeptide transporter PepT1 (SLC15 family), was injected in Xenopus oocytes that were subsequently tested with electrophysiological techniques. Transport-associated currents were observed when various di- or tripeptides were applied at concentrations ranging between 0.1 and 10 mM. No currents were generated by histidine nor by other single amino acids. Sea bass PepT1 also exhibited pre… Show more

“…It has been found in a wide range of organisms, from bacteria to humans (Leibach and Ganapathy, 1996; Daniel et al, 2006), including many fish species (Verri et al, 2003; Sangaletti et al, 2009; Terova et al, 2013; Hart et al, 2016). PepT is a co-transporter, moving small peptides into the enterocytes.…”

“…However, in sea bass the data show that, as in higher vertebrates, the maximum transport activity of PepT1 is almost independent of extracellular pH (Sangaletti et al . ), which suggests the occurrence of species‐specific adaptations in the functional behaviour of the transporter.…”
