Calculation of proton transfers in Bacteriorhodopsin bR and M intermediates.
Residue ionization states were calculated in nine crystal structures of bacteriorhodopsin trapped in bR, early M, and late M states by multiconformation continuum electrostatics. This combines continuum electrostatics and molecular mechanics, deriving equilibrium distributions of ionization states and polar residue and water positions. The three central cluster groups [retinal Schiff base (SB),...
متن کاملThe 1s photoabsorption transitions in Br I and Br II
Relativistic configuration interaction calculations have been performed for the 1s→np (n=4-8) photoabsorption transitions in Br I and Br II and transition energies and transition probabilities have been evaluated. These data are necessary to interpret the experiment photoabsorption spectra. The K edge energy of Br I and Br II have also been computed and compared to the existing values when avai...
متن کاملPHOTOCYCLE AND PROTON TRANSLOCATION IN BACTERIORHODOPSIN Bacteriorhodopsin (bR), a natural photochromic protein from Halobacterium salinarum (formerly H. halo
This review deals with the role of carboxylic amino acids in the proton transport activity of bacteriorhodopsin. The main focus is on the infrared data, which allow direct monitoring of the protonation/deprotonation of specific residues dur ing the proton movement in the course of the photocycle. Additional attention is paid to the potential use of carboxylic acids in proteins as internal senso...
متن کاملDetecting conformational change by current transport in proteins: The case of bacteriorhodopsin monolayers
Recent experiments on the light receptor bacteriorhodopsin have revealed the protein conductive properties and connected them to its sensing action. In particular it was shown that the super-Ohmic I-V characteristic acquired in dark, changes in the presence of green light, with an enhancement of current at increasing bias values. Here we propose a current transport model for proteins able to re...

Loss of Imprinting (LOI) of IGF2 and over-expressed IGF2 are associated with tumorigenesis. Our previous epidemiological study found a relatively high frequency of IGF2 LOI in healthy mid-gestation pregnant women. The aim of this study is to determine whether the expression of IGF2 is associated with its imprinting status in healthy Chinese pregnant women. The IGF2 imprinting status of 300 preg...
