Stability of bacteriorhodopsin alpha-helices and loops analyzed by single-molecule force spectroscopy

, 2002
The combination of high-resolution atomic force microscopy imaging and single-molecule force spectroscopy allows the identification, selection, and mechanical investigation of individual proteins.

34 CHEMICAL MODIFICATION OF RETINAL MOIETY IN PURPLE MEMBRANE

, 1981
The purpose of this study on photoreception of modified bacteriorhodopsins involves obtaining information on the structure of the protein by chemically analyzing bacteriorhodopsins which are reconstituted with artificial retinals and the opsin, and by ...

Enthalpy changes during the photochemical cycle of bacteriorhodopsin

, 1979
We have used a capacitor microphone calorimeter to measure rapid enthalpy changes that occur when bacteriorhodopsin-containing membrane fragments are excited with short flashes of light. We resolved the enthalpy changes into three phases.

Spektroskopische Untersuchungen an Isomeren des Bacteriorhodopsins

, 1981
Artificial BR isomers are formed in vitro with 7-cis and 7,13-dicis retinal as chromophores : In contrast to the native BR this artificial BR system allows us to measure physico-chemical parameters which help us to understand the native BR system - BR$_ ...

Aspartic acids 96 and 85 play a central role in the function of bacteriorhodopsin as a proton pump

, 1989
A spectroscopic and functional analysis of two point-mutated bacteriorhodopsins (BRs) from phototrophic negative halobacterial strains is reported. Bacteriorhodopsin from strain 384 contains a glutamic acid instead of an aspartic acid at position 85 and ...

Homologues of archaeal rhodopsins in plants, animals and fungi: structural and functional predications for a putative fungal chaperone protein

, 2001
The microbial rhodopsins (MR) are homologous to putative chaperone and retinal-binding proteins of fungi. These proteins comprise a coherent family that we have termed the MR family. We have used modeling techniques to predict the structure of one of the
