Conjugated Cofactor Enables Efficient Temperature-Independent Electronic Transport Across ∼6 nm Long Halorhodopsin

, 2015
We observe temperature-independent electron transport, characteristic of tunneling across a ∼6 nm thick Halorhodopsin (phR) monolayer. phR contains both retinal and a carotenoid, bacterioruberin, as cofactors, in a trimeric protein-chromophore complex ...

Effect of hydrogen index and sodium chloride concentration on bacterioruberin biosynthesis

Processes and Food Production Equipment
This study investigated the effect of sodium chloride (NaCl) concentration and medium pH on the ability of Arthrobacter agilis wb28 to synthesize bacterioruberin. This compound is a carotenoid in nature and plays a functional role in protecting the cell against environmental stress, including oxidative and osmotic stress; therefore, it has attracted ...

Spectroscopic Characterization of Halorhodopsin Reconstituted into Nanodisks Using Native Lipids

, 2020
We successfully reconstituted single Natronomonas pharaonis halorhodopsin (NpHR) trimers into a nanodisk (ND) using the native archaeal lipid (NL) and an artificial lipid having a zwitterionic headgroup, 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine ...
