| Method |
P.12669 left column bottom paragraph: "To learn more about the binding of CheY∼P to FliM and about the kinetics of the chemotactic response, [investigators] extended [their] recent analysis of phosphorylation-dependent interactions of CheY with CheZ (ref 9) and measured fluorescence resonance energy transfer (FRET) between cyan fluorescent protein (CFP) fused to the N terminus of FliM (CFP-FliM) and yellow fluorescent protein (YFP) fused to the C terminus of CheY (CheY-YFP). The FRET technique relies on the distance-dependent transfer of energy from an excited donor fluorophore (CFP) to an acceptor fluorophore (YFP) and allows one to monitor changes in protein interactions in real time in vivo (refs 10, 11)." |
| Comments |
p.12670 left column bottom paragraph: "The level of expression of CFP-FliM in [investigators'] standard experiment, necessary for optimum complementation of motility, was about three times higher than the level of FliM in the wild type (1.7–2.0 μM primary sources)." Primary sources [14] & [15] investigated E. coli & S. typhimurium, respectively. |
