== Publication Abstract from PubMed == | |||
The thermophilic bacterium Thermus aquaticus is a well-known source of Taq polymerase. Here, we studied the structure and dynamics of the T. aquaticus cold-shock protein (Ta-Csp) to better understand its thermostability using NMR spectroscopy. We found that Ta-Csp has a five-stranded beta-barrel structure with five salt bridges which are important for more rigid structure and a higher melting temperature (76 degrees C) of Ta-Csp compared to mesophilic and psychrophilic Csps. Microsecond to millisecond time scale exchange processes occur only at the beta1-beta2 surface region of the nucleic acid binding site with an average conformational exchange rate constant of 674s-1. The results imply that thermophilic Ta-Csp has a more rigid structure and may not need high structural flexibility to accommodate nucleic acids upon cold shock compared to its mesophile and psychrophile counterparts. | |||
