  1. Two model comparisons were conducted; each comparison includes a neutral model (M1a, M7) and a model allowing for positive selection (M2a, M8). Significance was assessed by comparing twice the difference in likelihood 2(Lb-La) between the models to a χ2-distribution (df = 2). The models fitting our data best are marked in bold. x marks positively selected codons calculated by Bayes Empirical Bayes (BEB) at the >95% confidence level. Distance (Dist.) to Tong PBR corresponds to the amino acid distance between identified site and the nearest peptide binding position identified by Tong et al. [73].
