The Phosphoenolpyruvate-dependent Sugar Phosphotransferase System (PTS) is a major carbohydrate active transport system that catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. The PTS is involved in the transport of various sugars including beta-glucosides, sucrose, trehalose, N-acetylmuramic acid, and MurNAc-GlcNAc. It consists of multiple domains: EIIC forms the translocation channel with a substrate-binding site; EIIB is phosphorylated by phospho-EIIA on a cysteinyl or histidyl residue, depending on the sugar, and transfers the phosphoryl group to the sugar substrate; EIIA is phosphorylated by phospho-HPr on a histidyl residue and transfers the phosphoryl group to EIIB. The system plays a key role in the uptake and phosphorylation of sugars, facilitating their utilization as carbon and energy sources, and is involved in the regulation of various cellular processes.
