Time-resolved fluorescence of 2-aminopurine as a probe of base flipping in M.HhaI–DNA complexes
DNA base flipping is an important mechanism in molecular enzymology, but its study is limited by the lack of an accessible and reliable diagnostic technique. A series of crystalline complexes of a DNA methyltransferase, M.HhaI, and its cognate DNA, in which a fluorescent nucleobase analogue, 2-aminopurine (AP), occupies defined positions with respect the target flipped base, have been prepared ...
متن کاملCorrelation Spectroscopy , and Time Resolved Fluorescence Anisotropy Decay
Research Summary: An increase of the alkyl chain length of the cation of room temperature ionic liquids (RTILs) influences the nanoscale structure and dynamics of RTILs, which in turn affect the behavior of RTILs at solid-liquid interfaces central to energy storage devices. We integrate classical molecular dynamics (CMD) simulation, fluorescence correlation spectroscopy (FCS), time resolved flu...
متن کاملTime-resolved fluorescence anisotropy imaging applied to live cells.
We have developed a wide-field time-resolved imaging system to image quantitatively both the fluorescence lifetime and the rotational correlation time of a fluorophore. Using a polarization-resolved imager, we simultaneously image orthogonal polarization components of the fluorescence emission onto a time-gated intensified CCD. We demonstrate imaging of solvent viscosity variations through the ...
متن کاملTime Resolved Fluorescence Anisotropy of Basic Dyes Bound to Poly(methacrylic acid) in Solution
Soluções de poli(ácido metacrílico) atático, PAMA com peso molecular na faixa de (1,6 a 3,4) x 10 g mol, e com corantes fluorescentes 9-aminoacridina ou azul do nilo ligados à cadeia, foram estudados por medidas fotofísicas em função da viscosidade e polaridade do solvente. O comportamento dos segmentos da cadeia do PAMA nas vizinhanças da sonda fluorescente foi descrito pela mudança na rotação...
متن کاملApplication of Interpolymer Complexation of Polyvinyl-
Interpolymer complex formation of polyvinylpyrrolidone (PVP) with carboxyvinyl polymer (CP) was examined by turbidity measurement, a binding isotherm study and Fourier-transform infrared spectroscopy. The interpolymer complex of PVP with CP was found to be formed in the unit molecular ratio of 1: 1 under ideal conditions, though the ratio of PVP in the solid complex was lower than 1: 1 under pr...
