    We report a crystallographic and computational analysis of two mutant forms of the Alicyclobacillus acidocaldarius thioredoxin (BacTrx) done in order to evaluate the contribution of two specific amino acids to the thermostability of BacTrx. Our results suggest that the thermostability of BacTrx may be modulated by mutations affecting the overall electrostatic energy of the protein.
