Journal ArticleDOI
Interaction of G-quadruplex with RecA protein studied in bulk phase and at the single-molecule level.
TL;DR: In this article, the RecA@ssDNA filament, which is formed by the interaction between RecA protein and a G-rich sequence, was dissociated by the addition of K(+) ions, and the dissociated Grich sequence was quickly folded to the G-quadruplex structure.
Journal ArticleDOI
Photo-induced DNA scission by Cu(II)-meso-tetrakis(n-N-methylpyridiniumyl)porphyrins (n = 2, 3, 4) and their binding modes to supercoiled DNA
TL;DR: Lower linear dichroism spectroscopy showed angles of o-CuTMPyP's electric transition moments, in which the periphery pyridinium ring was prevented from free rotation, of 59° and 61° with respect to the local DNA helix axis, indicating that hydroxyl radicals and singlet oxygen were likely reactive species responsible for the cleavage.
Journal ArticleDOI
Excited state properties of the n‐(deoxyguanosin‐8‐yl)‐2‐aminofluorene adducts
L. P.A. van Houte,R. van Grondelle,J. Retel,J.G. Westra,D. ZlNGER,John C. Sutherland,Seog K. Kim,Nicholas E. Geacintov +7 more
TL;DR: The disappearance of the exciplex emission at low temperatures suggests that the excited state interactions in these dGuo‐C8‐AF adducts at room temperature involve some conformational mobility of the two covalently linked moieties.
Journal ArticleDOI
Retained binding mode of various DNA-binding molecules under molecular crowding condition
TL;DR: The results suggest that the transition moments are not expected to be perturbed significantly by PEG molecules, and there was no need to focus on the conformational changes of the DNA helical structure, such as forming irregular aggregate structures, induced by large quantities of molecular crowding media itself at this stage.
Journal ArticleDOI
Effects of intercalators on complexation of RecA with duplex DNA.
TL;DR: Judged by circular dichroism, similar RecA conformational changes accompanied bis-9-aminoacridine- and ATP gamma S-induced RecA association with DNA.
