aOnly the transmembrane helical segments and the two loop regions (Ω and S) were considered for pairwise sequence alignments
bNumbers shown in bold are average of percent sequence identity and similarity for all possible pairs within the specified subgroup. Sequence similarity values are shown in brackets
