Glutamine synthetase sequence evolution in the mycobacteria and their use as molecular markers for Actinobacteria speciation.

abstract：BACKGROUND:Small heat shock proteins (sHSPs) are products of heat shock response and of other stress responses, and ubiquitous in all three domains of life, archaea, bacteria, and eukarya. They mainly function as molecular chaperones to protect proteins from being denatured in extreme conditions. Study on insect sHSPs ...
