The polymerization reaction was followed either by an increase in pyrene-labeled actin fluorescence or by a decrease in intrinsic fluorescence in the absence of pyrene-labeled actin. pyrene 229-235 actin Saccharomyces cerevisiae S288C 29-34 8552682-1 1996 Wild-type actin and a mutant actin were isolated from yeast (Saccharomyces cerevisiae) and the polymerization properties were examined at pH 8.0 and 20 degrees C. The polymerization reaction was followed either by an increase in pyrene-labeled actin fluorescence or by a decrease in intrinsic fluorescence in the absence of pyrene-labeled actin. pyrene 229-235 actin Saccharomyces cerevisiae S288C 29-34 8552682-1 1996 Wild-type actin and a mutant actin were isolated from yeast (Saccharomyces cerevisiae) and the polymerization properties were examined at pH 8.0 and 20 degrees C. The polymerization reaction was followed either by an increase in pyrene-labeled actin fluorescence or by a decrease in intrinsic fluorescence in the absence of pyrene-labeled actin. pyrene 229-235 actin Saccharomyces cerevisiae S288C 29-34 8552682-5 1996 Second, as measured with pyrene-labeled yeast actin, but not with intrinsic fluorescence, there is an overshoot in the fluorescence that has not been observed with skeletal muscle actin under the same conditions. pyrene 25-31 actin Saccharomyces cerevisiae S288C 46-51 11959868-3 2002 Pyrene at each of these positions produced differing fluorescence spectra in G-actin. pyrene 0-6 actin Saccharomyces cerevisiae S288C 79-84 11959868-8 2002 F-actin quenching was biphasic for the 265, 266, and 269 but not 267 probes, suggesting that in F-actin, the pyrene samples multiple environments. pyrene 109-115 actin Saccharomyces cerevisiae S288C 2-7 11959868-8 2002 F-actin quenching was biphasic for the 265, 266, and 269 but not 267 probes, suggesting that in F-actin, the pyrene samples multiple environments. pyrene 109-115 actin Saccharomyces cerevisiae S288C 98-103 11959868-9 2002 Finally, in F-actin the probe at 266 interacts with one at Cys(374) on a monomer in the opposing strand, producing a pyrene excimer band. pyrene 117-123 actin Saccharomyces cerevisiae S288C 14-19 10677229-9 2000 This demonstrates a transition at the S1 contact with actin"s N-terminus between the weakly and strongly bound states, and implies either a closer proximity of the pyrene probe on Cys-1 to structural elements on S1 (most likely the loop of residues 626-647) or greater S1-induced changes at the N-terminus of actin in the weakly bound acto-S1 states. pyrene 164-170 actin Saccharomyces cerevisiae S288C 54-59
