Cyanobacterial Two-Component Proteins: Structure,Diversity, Distribution, andEvolution

Cyanobacterial two-component proteins: structure, diversity, distribution, and evolution.

A survey of the already characterized and potential two-component protein sequences that exist in the nine complete and seven partially annotated cyanobacterial genome sequences available (as of May 2005) showed that the cyanobacteria possess a much larger repertoire of such proteins than most other bacteria. By analysis of the domain structure of the 1,171 potential histidine kinases, response...

Evolution and phyletic distribution of two-component signal transduction systems.

Two-component signal transduction systems are abundant in prokaryotes. They enable cells to adjust multiple cellular functions in response to changing environmental conditions. These systems are also found, although in much smaller numbers, in lower eukaryotes and plants, where they appear to control a few very specific functions. Two-component systems have evolved in Bacteria from much simpler...

Electric microfield distribution in two-component plasmas. Theory and Simulations

The distribution of the electric microfield at a charged particle moving in a two-component plasma is calculated. The theoretical approximations are obtained via the parameter integration technique and using the screened pair approximation for the generalized radial distribution function. It is shown that the two-component plasma microfield distribution shows a larger probability of high microf...

Microfield distribution in an ion-electron two-component plasma

The profiles of spectral lines of a radiator (atom or ion) immersed in a plasma are a valuable diagnostic tool [1]. Under certain conditions [1, 2], the observed line shapes are closely related to the electric microfield distribution (MFD) at the position of the radiator [2]. Since the pioneering work of Holtsmark [2], various theoretical approaches to determine the MFD have been proposed. Most...
