Abstract

In eukaryotes, cellular energy in the form of ATP is produced in the cytosol via glycolysis or in the mitochondria via oxidative phosphorylation and, in photosynthetic organisms, in the chloroplast via photophosphorylation. Transport of adenine nucleotides among cell compartments is essential and is performed mainly by members of the mitochondrial carrier family, among which the ADP/ATP carriers are the best known. This work reviews the carriers that transport adenine nucleotides into the organelles of eukaryotic cells together with their possible functions. We focus on novel mechanisms of adenine nucleotide transport, including mitochondrial carriers found in organelles such as peroxisomes, plastids, or endoplasmic reticulum and also mitochondrial carriers found in the mitochondrial remnants of many eukaryotic parasites of interest. The extensive repertoire of adenine nucleotide carriers highlights an amazing variety of new possible functions of adenine nucleotide transport across eukaryotic organelles.

摘要

在真核生物中,细胞能量以 ATP 的形式通过糖酵解在线粒体中产生,或者通过氧化磷酸化在真核生物中产生,在光合生物中通过光合磷酸化产生。腺嘌呤核苷酸在细胞区室之间的运输是必不可少的,主要由线粒体载体家族的成员完成,其中最著名的是 ADP/ATP 载体。这项工作综述了将腺嘌呤核苷酸转运到真核细胞细胞器的载体及其可能的功能。我们专注于腺嘌呤核苷酸转运的新机制,包括在过氧化物酶体、质体或内质网等细胞器中发现的线粒体载体,以及在许多有研究价值的真核寄生虫线粒体残余物中发现的线粒体载体。腺嘌呤核苷酸载体的广泛组成突出了腺嘌呤核苷酸跨真核细胞器运输的令人惊讶的多种新的可能功能。
