Dissimilar orthologs
 DNA polymerase III, gamma and tau subunitDR24102583049Significant differences in protein length (variation in C-terminal tail)
 DNA polymerase XDR04671526547 D. radiodurans contains an additional PHP domain, which is present also in B. subtilisand M. thermoautotrophicum; the polymerase domain inDeinococcus appears to be inactivated
Acetolactate synthase, large subunitDR15161311482The similarity between the Deinococcus and Thermus proteins is low compared to the similarity between each of them and orthologs from other bacteria
