Method Researchers used fluorescence recovery after photobleaching (FRAP) along with a detailed numerical model that simulates FRAP experiments, to systematically investigate mobility of cytoplasmic, inner membrane, and DNA-binding proteins in Escherichia coli.
Comments Estimated diffusion coefficients of plasma membrane proteins, 0.22–0.02µm^2/sec, agree well with the values previously reported for TatA-GFP (refs 4,20) and CydB-GFP (ref 21) fusions in E. coli.
