Phytochromes in Agrobacterium fabrum

Frontiers in Plant Science, 2021
The focus of this review is on the phytochromes Agp1 and Agp2 of Agrobacterium fabrum. These are involved in regulation of conjugation, gene transfer into plants, and other effects. Since crystal structures of both phytochromes are known, the phytochrome

The Goldbeter-Koshland switch in the first-order region and its response to dynamic disorder [PDF]

, 2008
In their classical work (Proc. Natl. Acad. Sci. USA, 1981, 78:6840-6844), Goldbeter and Koshland mathematically analyzed a reversible covalent modification system which is highly sensitive to the concentration of effectors.

Identification of Alternative Polyadenylation in Cyanidioschyzon merolae Through Long-Read Sequencing of mRNA

Frontiers in Genetics, 2022
Alternative polyadenylation (APA) is widespread among metazoans and has been shown to have important impacts on mRNA stability and protein expression. Beyond a handful of well-studied organisms, however, its existence and consequences have not been well ...

Recent Approaches on Signal Transduction and Transmission in Acupuncture: A Biophysical Overview for Medical Sciences

Journal of Acupuncture and Meridian Studies, 2020
Acupuncture is one of the areas among the alternative therapies that arise high curiosity in the biomedical scientific community. It is particularly popular for treatment of chronic diseases and addictions. However, contrasting with its evidence-based effectiveness, the lack of reasonable explanations for its mode of action divides that scientific ...

Impact of an electric field on P-type ATPases [PDF]

, 2008
P-type ATPases are membrane proteins acting as ion pumps that drive an active transport of cations across the membrane against a concentration gradient. The required energy for the ion transport is provided by binding and hydrolysis of ATP.

Biophysical mechanisms of intracellular signaling (transduction) in higher plants

Proceedings of the National Academy of Sciences of Belarus, Biological Series, 2023
Three fundamental processes running in plant organisms under influence of environment (light, gravity) and key importance were considered. In the light case these are phytоchrome regulation and phototropism considering process is gravitropism. Phytochrome is responsible for regulatory reaction at the inhibition of which the plants cannot be normally ...

Energy-based Analysis of Biochemical Cycles using Bond Graphs [PDF]

, 2014
Thermodynamic aspects of chemical reactions have a long history in the Physical Chemistry literature. In particular, biochemical cycles - the building-blocks of biochemical systems - require a source of energy to function.
