A general strategy for site-specific double labeling of globular proteins for kinetic FRET studies.
Authors:Ratner V,Kahana E,Eichler M,Haas E
Journal:Bioconjugate chemistry
PubMed ID:12236801
Site-directed mutagenesis provides a straightforward means of creating specific targets for chemical modifications of proteins. This capability enhanced the applications of spectroscopic methods adapted for addressing specific structural questions such as the characterization of partially folded and transient intermediate structures of globular proteins. Some applications such as the steady state ... More
Membrane translocation of charged residues at the tips of hydrophobic helices in the T domain of diphtheria toxin.
Authors:Ren J, Sharpe JC, Collier RJ, London E
Journal:Biochemistry
PubMed ID:9893993
'The low pH triggered membrane insertion of the T domain of diphtheria toxin is a critical step in the translocation of the C domain of the toxin across membranes in vivo. We previously established that the T domain can interact with membranes in two distinct conformations, one in which the ... More
Topography of diphtheria toxin A chain inserted into lipid vesicles.
Authors:Hayashibara M, London E
Journal:Biochemistry
PubMed ID:15697244
'The membrane-inserting T domain of diphtheria toxin aids the low-pH-triggered translocation of the catalytic A chain of the toxin across endosomal membranes. To evaluate the role of the isolated A chain in translocation, the topography of isolated A chain inserted into model membrane vesicles was investigated using a mixture either ... More
Topography of the hydrophilic helices of membrane-inserted diphtheria toxin T domain: TH1-TH3 as a hydrophilic tether.
Authors:Wang J, Rosconi MP, London E
Journal:Biochemistry
PubMed ID:16800637
'After low pH-triggered membrane insertion, the T domain of diphtheria toxin helps translocate the catalytic domain of the toxin across membranes. In this study, the hydrophilic N-terminal helices of the T domain (TH1-TH3) were studied. The conformation triggered by exposure to low pH and changes in topography upon membrane insertion ... More
