Hi Hsu, You can check my paper. We have done a similar analysis of several factors responsible for thermal stability, analysis done using various mesophiles and thermophiles, Crystal structure of the *Bacillus anthracis* nucleoside diphosphate kinase and its characterization reveals an enzyme adapted to perform under stress conditions.
