  ABSTRACT  
 
Integral beta-barrel proteins are found in the outer membranes of mitochondria, chloroplasts, and Gram-negative bacteria. The machine that assembles these proteins contains an integral membrane protein, called YaeT in Escherichia coli, which has one or more polypeptide transport-associated (POTRA) domains. The crystal structure of a periplasmic fragment of YaeT reveals the POTRA domain fold and suggests a model for how POTRA domains can bind different peptide sequences, as required for a machine that handles numerous beta-barrel protein precursors. Analysis of POTRA domain deletions shows which are essential and provides a view of the spatial organization of this assembly machine.

Fig. 2. Structure of YaeT. (A) Domain organization. (B) X-ray structure of YaeT[21-351]. POTRA domains P1 to P4 are colored yellow, green, blue, and red, respectively. The eight residues from P5 are colored gray. The missing electron density in the P3 domain is represented by a dashed line. (C) Ribbon diagram of a POTRA domain (P2) with side chains of the conserved residues shown. (D) Sequence alignments of POTRA domains from selected members of the YaeT/Omp85, Sam50, and Toc75 families, found in Gram-negative bacteria, mitochondria, and chloroplasts or cyanobacteria, respectively [adapted from Sánchez-Pulido et al. (14)]. Conserved residues are highlighted (28). The intensity of the orange color reflects the level of conservation in physicochemical properties. (E) X-ray structure of the dimer. The POTRA domains in one monomer are colored as in (B); the other monomer is purple. (F) Dimer interface showing the C-terminal residue contacts of one monomer (gray) to the P2 (light green) and P3 (light blue) domains of the other monomer. Labels represent hydrophobic residues.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
