This review examines the photophysical properties of an interesting and biologically important class of proteins known as the rhodopsins. The visual rhodopsins are responsible for the conversion ofExpand
Biomolecular Electronics: Protein-Based Associative Processors and Volumetric Memories
The light-transducing protein bacteriorhodopsin provides not only an efficient photonic material, but also a versatile template for device creation and optimization via both chemical modification and genetic engineering. Expand
On the molecular origin of photoreceptor noise
It is proposed that photoreceptor noise results from the thermal isomeriz-ation of a relatively unstable form of rhodopsin, one in which the Schiff-base linkage between the chromophore and protein is unprotonated. Expand
Raman Spectroscopic Study of Kaolinite in Aqueous Suspension
The vibrational modes of clay minerals in aqueous suspension are uniquely accessible to Raman spectroscopy, but this potentially powerful approach has not been applied heretofore to study clays inExpand
Structural control of the photodynamics of boron-dipyrrin complexes.
The combined results demonstrate the critical role of aryl-ring rotation in governing the excited-state dynamics of this class of widely used dyes. Expand
THz time domain spectroscopy of biomolecular conformational modes.
The measured absorbances of terahertz time domain spectroscopy of several biomolecular systems are compared and it is found that the TTDS absorbance reflects the density of normal modes determined by molecular mechanics calculations, and is sensitive to both conformation and mutation. Expand
Protein flexibility and conformational state: a comparison of collective vibrational modes of wild-type and D96N bacteriorhodopsin.
These results represent the first measurement of FIR absorbance change as a function of conformational state and are compared to calculated spectra generated via normal mode analyses using CHARMM. Expand
Coherent Control of Retinal Isomerization in Bacteriorhodopsin
Modulating the phases and amplitudes of the spectral components in the photoexcitation pulse showed that the absolute quantity of 13-cis retinal formed upon excitation can be enhanced or suppressed by ±20% of the yield observed using a short transform-limited pulse having the same actinic energy.
