Blue bacteria adversity adaptation mechanism key: histamine kinase Hik33.

Blue bacteria are important photolysal microorganisms and important manufacturers of oxygen in the Earth's atmosphere.
bacteria can survive in a variety of harsh and changing natural environments, but the mechanism by which they adapt to these adversity and survive is unclear.
The Wang Yingchun Research Group of the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences, using quantitative proteomics, found that hytonephase Hyk33 of the blue bacterial binary signaling system was able to regulate a wide spectrum of proteins that respond to a variety of adversity and photodeprotective proteins.
When blue bacteria are subjected to adversity stress, Hik33 can reasonably distribute material and energy resources by raising the protein associated with adversity adaptation and lowering the protein associated with photodepending, and slow the proliferation of blue bacteria to achieve the goal of adaptation and survival of adversity.
the results have been published online in Molecular and Cell Proteomics (Molecular and Cellular Proteomics, DOI: 10.1074/mcp. M117.068080).
