Hard-Wired Solid-State Bioelectronic Micropore Devices: Permanent Metal-Protein-Metal Junction Proof-of-Concept. [PDF]
SmallA bottom‐up way to fabricate precisely engineered micropore solid‐state metal substrate/protein film / evaporated metal structures is shown to be a versatile platform for systematic electron transport measurements. As protein function is preserved and the junctions are thermally stable, down to 10K, such junctions can be useful for bioelectronic ...

Without Contact Resistance, Proteins in Thin-Film Solid-State Junctions Can Be Efficient Electronic Conducting Materials. [PDF]
Adv MaterIt is demonstrated that contact resistance is effectively eliminated in two‐probe micropore device metal/protein/metal bioelectronic junctions. These results, using two different protein types in these junctions, show that, as ultrathin (<40 nm) films, proteins are an even more efficient electronic transport medium than previously thought, when the ...

Crystal structure of Escherichia coli-expressed Haloarcula marismortui bacteriorhodopsin I in the trimeric form. [PDF]
PLoS ONE, 2014 Bacteriorhodopsins are a large family of seven-helical transmembrane proteins that function as light-driven proton pumps. Here, we present the crystal structure of a new member of the family, Haloarcula marismortui bacteriorhodopsin I (HmBRI) D94N mutant,

Annual Review of Physiology, 1999 ▪ Abstract Fourier transform infrared and Raman spectroscopy, solid-state NMR, and X-ray crystallography have contributed detailed information about the structural changes in the proton transport cycle of the light-driven pump, bacteriorhodopsin. The results over the past few years add up to a step-by-step description of the configurational changes ...

Artificial photosynthetic cell producing energy for protein synthesis
Nature Communications, 2019 Artificial cells need to be supplied with ATP as they lack internal systems of energy generation. Here the authors reconstruct ATP synthase and bacteriorhodopsins for light-driven ATP generation, powering transcription and translation.

Cation binding by bacteriorhodopsin [PDF]
Proceedings of the National Academy of Sciences, 1985 We have found that extensively washed purple membrane has about 1 calcium and 3-4 magnesium ions bound per bacteriorhodopsin molecule. When these divalent cations are removed by any of a variety of means, the pigment changes its color from purple to blue (λ max ≈ 600 nm).
