An assessment of the resolution limitation due to radiation-damage in x-ray diffraction microscopy

open access: yes, 2005
X-ray diffraction microscopy (XDM) is a new form of x-ray imaging that is being practiced at several third-generation synchrotron-radiation x-ray facilities.

Time-Resolved Resonance Raman Spectroscopy of Retinal Proteins with Continuous-Wave Excitation—A Fundamental Methodology Revisited

open access: yesPhotochem
Time-resolved (TR) resonance Raman (RR) spectroscopy with continuous-wave excitation is a fundamental technique that has contributed substantially to the understanding of the structure and dynamics of retinal proteins.

Hierarchy and assortativity as new tools for affinity investigation: the case of the TBA aptamer-ligand complex

open access: yes, 2017
Aptamers are single stranded DNA, RNA or peptide sequences having the ability to bind a variety of specific targets (proteins, molecules as well as ions).

Electrostatics and electrodynamics of bacteriorhodopsin

open access: yesBiophysical Journal, 1996
The stationary electric dichroism of bacteriorhodopsin is in qualitative, but not quantitative, agreement with the orientation function for disks having a permanent dipole directed perpendicular to the plane and an induced dipole in the plane. Fits of the orientation function to data measured at low field strengths demonstrate: an increase of the ...

Three-dimensional view of ultrafast dynamics in photoexcited bacteriorhodopsin in the multiphoton regime and biological relevance

open access: yesNature Communications, 2020
How does chemistry scale in complexity to unerringly direct biological functions? Nass Kovacs et al. have shown that bacteriorhodopsin undergoes structural changes tantalizingly similar to the expected pathway even under excessive excitation.

Dynamics of active membranes with internal noise

open access: yes, 2005
We study the time-dependent height fluctuations of an active membrane containing energy-dissipating pumps that drive the membrane out of equilibrium.

Unravelling the folding of bacteriorhodopsin

open access: yesBiochimica et Biophysica Acta (BBA) - Bioenergetics, 2000
The folding mechanism of integral membrane proteins has eluded detailed study, largely as a result of the inherent difficulties in folding these proteins in vitro. The seven-transmembrane helical protein bacteriorhodopsin has, however, allowed major advances to be made, not just on the folding of this particular protein, but also on the factors ...

Lipidic cubic phase injector is a viable crystal delivery system for time-resolved serial crystallography

open access: yesNature Communications, 2016
Serial femtosecond crystallography using X-ray free-electron lasers has huge potential for time-resolved structural experiments. Here, the authors present a structure of the light-driven proton pump bacteriorhodopsin using these techniques.

Mixed Potential Energy Surfaces of the Ultrafast Isomerization of Retinal in Bacteriorhodopsin

open access: yesEPJ Web of Conferences, 2013
We observe, using electronic two-dimensional photon echo spectroscopy, that the cis and trans potential energy surfaces of the ultrafast isomerization of retinal in bacteriorhodopsin are mixed via the hydrogen out of plane (HOOP) mode.
