Study of light-induced formation of photodimers in the i-motif nucleic acid structure by rapid-scan FTIR difference spectroscopy and hybrid hard- and soft-modelling

The i-motif is a DNA structure formed by cytosine-rich sequences. To provide a different view on the light-induced structural changes and dynamics of direct excitation processes involving i-motif structures, the use of rapid-scan FTIR spectroscopy and hybrid hard- and soft-modelling are proposed.

Light-induced structural changes during early photo-intermediates of the eubacterial Cl−pump Fulvimarina rhodopsin observed by FTIR difference spectroscopy

Fulvimarina pelagirhodopsin (FR) is a member of inward eubacterial light-activated Cl−translocating rhodopsins (ClR) that were found recently in marine bacteria.
