Programmed -1 ribosomal frameshifting (-1PRF) is tightly regulated by messenger RNA (mRNA) sequences and structures in expressing two or more proteins with precise ratios from a single mRNA. Using single-molecule fluorescence resonance energy transfer (smFRET) between (Cy5)EF-G and (Cy3)tRNALys, we

Pseudomonas sp. strain TW3 is able to metabolize 4-nitrotoluene to 4-nitrobenzoate and toluene to benzoate aerobically via a route analogous to the upper pathway of the TOL plasmids. We report the cloning and characterization of a benzyl alcohol dehydrogenase gene
We describe theory, experiments, and analyses of three-color Förster resonance energy transfer (FRET) spectroscopy for probing sub-millisecond conformational dynamics of protein folding and binding of disordered proteins. We devise a scheme that uses single continuous-wave laser excitation of the donor
Organic fluorophores common to fluorescence-based investigations suffer from unwanted photophysical properties, including blinking and photobleaching, which limit their overall experimental performance. Methods to control such processes are particularly important for single-molecule fluorescence and fluorescence resonance energy transfer imaging where uninterrupted
Fluorescence applications requiring high photostability often depend on the use of solution additives to enhance fluorophore performance. Here we demonstrate that the direct or proximal conjugation of cyclooctatetraene (COT), 4-nitrobenzyl alcohol (NBA) or Trolox to the cyanine fluorophore Cy5 dramatically
