Phototriggered Apoptotic Cell Death (PTA) Using the Light-Driven Outward Proton Pump Rhodopsin Archaerhodopsin-3.

Journal of the American Chemical Society, 2022
Apoptosis is a type of programmed cell death that commonly occurs in multicellular organisms including humans and that is essential to eliminate unnecessary cells to keep organisms healthy.

Activation of the optogenetic pumps halorhodopsin and archaerhodopsin result in an unexpected potassium ion redistribution

Physiology, 2023
The optogenetic pumps halorhodopsin and archaerhodopsin are now common tools for directed silencing of specific neuronal cell classes. Halorhodopsin achieves neuronal silencing by pumping chloride ions into cells while archaerhodpsin silences cells by ...

Directional Self-assembly in Archaerhodopsin-Reconstituted Phospholipid Liposomes

Chinese Journal of Chemistry, 2005
This paper reports, for the first time, that Archaerhodopsin-4 (AR4) could be reconstituted into phospholipid liposomes by self-assembly. AR4 is a new membrane protein isolated from halobacteria H.sp. xz515 in a salt lake of Tibet, China. This is a bacteriorhodopsin (bR) like protein, function as a light-driven proton pump.

Structural Role of Bacterioruberin in the Trimeric Structure of Archaerhodopsin-2

Journal of Molecular Biology, 2008
Archaerhodopsin-2 (aR2), a retinal protein-carotenoid complex found in the claret membrane of Halorubrum sp. aus-2, functions as a light-driven proton pump. In this study, the membrane fusion method was utilized to prepare trigonal P321 crystals (a=b=98.2 A, c=56.2 A) and hexagonal P6(3) crystals (a=b=108.8 A, c=220.7 A).

An Australian halobacterium contains a novel proton pump retinal protein: Archaerhodopsin

Biochemical and Biophysical Research Communications, 1988
A bacterial strain collected from Western Australia carries all the specific features of Halobacteria, an extremely halophilic archaebacteria. This strain, Halobacterium sp. aus-1, contains a retinal protein which does differ from bacteriorhodopsin but still pumps out protons in the light. This novel proton pump is named "archaerhodopsin".

pH DEPENDENCE OF THE ABSORPTION SPECTRA AND PHOTOCHEMICAL TRANSFORMATIONS OF THE ARCHAERHODOPSINS

Photochemistry and Photobiology, 1994
Abstract—Two strains of archaebacteria have been found to contain light‐driven proton pumping pigments analogous to bacteriorhodopsin (bR) in Halobacterium salinarium. These proteins are called archaerhodopsin‐1 (aR‐1) and archaerhodopsin‐2 (aR‐2). Their high degree of sequence identity with bR within the putative proton channel enables us to draw some

Two Consecutive Polar Amino Acids at the End of Helix E are Important for Fast Turnover of the Archaerhodopsin Photocycle

Photochemistry and Photobiology, 2019
Archaerhodopsins (ARs) is one of the members of microbial rhodopsins. Threonine 164 (T164) and serine 165 (S165) residues of the AR from Halorubrum sp. ejinoor (HeAR) are fully conserved in ARs, although they are far from the proton transfer channel and ...

Crystal Structures of Archaerhodopsin-1 and -2: Common Structural Motif in Archaeal Light-driven Proton Pumps

Journal of Molecular Biology, 2006
Archaerhodopsin-1 and -2 (aR-1 and aR-2) are light-driven proton pumps found in Halorubrum sp. aus-1 and -2, which share 55-58% sequence identity with bacteriorhodopsin (bR), a proton pump found in Halobacterium salinarum. In this study, aR-1 and aR-2 were crystallized into 3D crystals belonging to P4(3)2(1)2 (a = b = 128.1 A, c = 117.6 A) and C222(1) (
