SUMMARY:Physics-Biology interface seminar: Emmanuel Margeat - Institut d'Op
 tique: Campus Polytechnique - 17 Oct 13 13:15
DESCRIPTION:Looking at transcription mechanisms with single molecule FRET\n
 Emmanuel Margeat (Centre de Biochimie Structurale\, Montpellier)\nExceptio
 nal seminar hosted by Karen Perronet\nSPECIAL DATE\, TIME AND LOCATION\nF
 örster Resonance Energy Transfer (FRET) allows measuring the distance bet
 ween two spectrally distinct fluorophores\, in the 20-100 Å range. When m
 onitored at the single molecule level\, smFRET is useful in resolving subp
 opulations\, or observing conformational changes as a function of time wit
 hin single macromolecular complexes in vitro. I will describe here the met
 hodologies used to measure FRET accurately on single biomolecular complexe
 s\, freely diffusing in solution or immobilized on surfaces. I will then f
 ocus on our studies on the mechanism of prokaryotic transcription such as 
 antitermination control by the antiterminator LicT\, and Rho-induced trans
 cription termination.\n
