Opsin vs opsin: new materials for biotechnological applications

open access: yes, 2014
The need of new diagnostic methods satisfying, as an early detection, a low invasive procedure and a cost-efficient value, is orienting the technological research toward the use of bio-integrated devices, in particular bio-sensors.

On the two forms of bacteriorhodopsin

open access: yesFEBS Letters, 1994
In our previous work [(1993) FEBS Lett. 313, 248‐250; (1993) Biochem. Int. 30,461‐469] M‐intermediate formation of wild‐type bacteriorhodopsin was shown to involve two components differing in time constants (τ1 = 60–70 μs and τ2 = 220–250 μs), which were suggested to reflect two independent pathways of M‐intermediate formation.

GRKs and arrestins: Nomenclature and functions in GPCR‐dependent and ‐independent signalling

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 11, Page 2619-2633, June 2026.
G protein‐coupled receptor (GPCR) kinases (GRKs) and arrestins play a critical role in the regulation of GPCR signalling. Historic names of mammalian GRKs were replaced by systematic ones in the 1990s; however, both kinds of names are currently in use for mammalian arrestins.

Bacteriorhodopsin–ZnO hybrid as a potential sensing element for low-temperature detection of ethanol vapour

open access: yesBeilstein Journal of Nanotechnology, 2016
Zinc oxide (ZnO) and bacteriorhodopsin (bR) hybrid nanostructures were fabricated by immobilizing bR on ZnO thin films and ZnO nanorods. The morphological and spectroscopic analysis of the hybrid structures confirmed the ZnO thin film/nanorod growth and ...

Direct and Label-Free Determination of Human Glycated Hemoglobin Levels Using Bacteriorhodopsin as the Biosensor Transducer

open access: yesSensors, 2020
Glycated hemoglobin (HbA1c) levels are an important index for the diagnosis and long-term control of diabetes. This study is the first to use a direct and label-free photoelectric biosensor to determine HbA1c using bacteriorhodopsin-embedded purple ...

Biomolecular imaging and electronic damage using X-ray free-electron lasers

open access: yes, 2010
Proposals to determine biomolecular structures from diffraction experiments using femtosecond X-ray free-electron laser (XFEL) pulses involve a conflict between the incident brightness required to achieve diffraction-limited atomic resolution and the ...
