Notes: Numbers correspond to the alignment shown in Figure 2. ^aAmino acids identified in model M8 by the Bayes empirical Bayes procedure [67] using Codeml. Only those sites predicted to be undergoing positive selection with a posterior probability >95% are presented in the table. The * indicates that the posterior probability is >95%, and ** shows that the probability is >99%. ^bAmino acid sites identified by FEL are identified with ^. ^cAmino acid sites identified by MEME are identified with ^.
