A POTluck of peptide transporters

Abstract

EMBO J (2012) 31 16, 3411–3421 doi:; DOI: 10.1038/emboj.2012.157

EMBO J (2010) 30 2, 417–426 doi:; DOI: 10.1038/emboj.2010.309

The uptake of diet-derived peptides is mediated by the conserved proton-dependent oligopeptide transporter (POT) family. Crystal structures of bacterial transporters in the inward-open conformation and in an occluded conformation published in The EMBO Journal provide structural insight into the proton-driven peptide transport cycle.

Figure 1
Alternating access mechanism of the proton-dependent oligopeptide transporter (POT) family. To the right, the PEPTSt transporter is shown in the inward-open conformation (Solcan et al, 2012, PDB 4APS), in the middle, the PEPTSo in the inward-occluded conformation (Newstead et al, 2011, PDB 2XUT). To the left, another protein of the Major Facilitator Family, the Fucose transporter is shown in the outward-facing conformation (Dang et al, 2010, PDB 3O7Q).
