Amino acid transport is a ubiquitous phenomenon and serves a variety of functions in prokaryotes, including supply of carbon and nitrogen for catabolic and anabolic processes, pH homeostasis, osmoprotection, virulence, detoxification, signal transduction and generation of electrochemical ion gradients. Many of the participating proteins have eukaryotic relatives and are successfully used as model systems for exploration of transporter structure and function. Distribution, physiological roles, functional properties, and structure-function relationships of prokaryotic α-amino acid transporters are discussed.
