    ..This chapter summarizes efforts as applied to the disulfide cross-link mutants of BamA and describes experimental methods used in our studies to determine that lateral opening of the barrel domain is required for function. ..
  4. Noinaj N, Buchanan S. Summary and Future Directions. Methods Mol Biol. 2015;1329:279-80 pubmed publisher
    ..It is anticipated that the next decade will further advance our knowledge of how the BAM complex is able to perform its unique and interesting function. ..

  7. Rollauer S, Sooreshjani M, Noinaj N, Buchanan S. Outer membrane protein biogenesis in Gram-negative bacteria. Philos Trans R Soc Lond B Biol Sci. 2015;370: pubmed publisher
    ..Here, we will review some of these recent discoveries that have advanced our understanding of the biogenesis of OMPs in Gram-negative bacteria, starting with synthesis in the cytoplasm to folding and insertion into the OM. ..
  8. Buchanan S, Lukacik P, Grizot S, Ghirlando R, Ali M, Barnard T, et al. Structure of colicin I receptor bound to the R-domain of colicin Ia: implications for protein import. EMBO J. 2007;26:2594-604 pubmed
    ..Functional data using full-length colicin Ia show that colicin I receptor is necessary for cell surface binding, and suggest that the receptor participates in translocation of colicin Ia across the outer membrane. ..
  9. Buchanan S. Bacterial metal detectors. Mol Microbiol. 2005;58:1205-9 pubmed
    ..The new structure extends our knowledge of transporter architecture and suggests how signalling may occur across the outer membrane. ..
