Microtubule Formation Using Two-Component Gel System
Journal of the American Chemical Society, 2007We report a two-component gel system in which an amphiphile group and aromatic cores act as organic gelators by the process of self-assembly. The shape and size of the aromatic cores have a pronounced effect on the gel properties and on structures such as fibers and microtubules.

Two-component systems in plant signal transduction
Trends in Plant Science, 2000In plants, two-component systems play important roles in signal transduction in response to environmental stimuli and growth regulators. Genetic and biochemical analyses indicate that sensory hybrid-type histidine kinases, ETR1 and its homologs, function as ethylene receptors and negative regulators in ethylene signaling.

Among the many regulatory schemes governing virulence potential, two-component systems have been found time and time again to play key roles. The structure-function relationships of the various domains, kinase, receiver, and HPt domains, of two-component systems are examined in this chapter, following the path of information from outside to inside a ...

Two-Component Sensory Transduction Systems in Phytobacteria
Annual Review of Phytopathology, 1992Prokaryotic plant pathogens and symbionts have dynamic lifestyles in which they fill multiple niches in their life cycles. These organisms must be able to compete successfully against other organisms, often in the soil and rhizo sphere, and also take advantage of very specialized plant habitats.

Partially neutral two-component systems
Physics of Particles and Nuclei Letters, 2010The formation of high-current electron beams whose charge is partially neutralized by ions with currents exceeding the limiting Alfven current is analytically considered. The results of a measurement of the parameters of high-current electron beams formed in a partially neutralized state and a numerical simulation of nonstationary processes in ...

The rotating rodent: A two component system?
European Journal of Pharmacology, 1978The hypothesis that the rotating rat requires both nigro-striatal and mesolimbic dopaminergic components for activity has been tested. 6-Hydroxydopamine lesions were induced unilaterally in either or both the ascending nigrostriatal and mesolimbic dopamine pathway. In one group of rats the nucleus accumbens was destroyed bilaterally with electrolesions.

Inhibitors of bacterial two-component signalling systems
Expert Opinion on Investigational Drugs, 2000Bacterial two-component regulatory systems (TCS) play a pivotal role in the process of infection. These signal transduction systems enable bacterial pathogens to mount an adaptive response and cope with diverse environmental stresses, including nutrient deprivation, antibiotic onslaught and phagocytosis.

Signalling pathways in two-component phosphorelay systems
Trends in Microbiology, 1999Two-component systems are characterized by phosphotransfer reactions involving histidine and aspartate residues in highly conserved signalling domains. Although the basic principles of signal transduction by these systems have been elucidated, several important aspects, such as their integration into more complex cellular regulatory networks and the ...

The FMN-dependent two-component monooxygenase systems
Archives of Biochemistry and Biophysics, 2010The FMN-dependent two-component monooxygenase systems catalyze a diverse range of reactions. These two-component systems are composed of an FMN reductase enzyme and a monooxygenase enzyme that catalyze the oxidation of various substrates. The role of the reductase is to supply reduced flavin to the monooxygenase enzyme, while the monooxygenase enzyme ...
