摘要

小肽转运载体1(PepT1)是H+/肽偶联的转运载体。该载体通过利用肠腔到肠细胞的质子梯度来转运二肽和三肽。PepT1对游离氨基酸、多肽在动物肠道内的转运调控具有重要作用。本文综述了PepT1的分类、生物学特征及功能,并探讨了影响PepT1活性调控的因素。

Abstract

Intestinal peptide transporter 1 (PepT1) is a transporter of H+/peptide coupling, which has a function to transport dipeptide and tripeptide by proton gradient from the intestinal cavity to the intestinal cells. PepT1 plays an important role in the regulation of free amino acids and polypeptide transportation in the intestine of animals. This paper reviewed the classification, biological characteristics and functions of PepT1, and the factors that regulate its activity.
