(A) Phylogenetic analysis of RNA sequences for the S gene (partial sequence). (B) Predicted coiled-coil regions in the deduced S-protein sequence. The coiled-coil regions were predicted by Stablecoil 1.0 with a 35-residue window width. The HR1 and HR2 regions are indicated. (C) HR1 and HR2 in the S protein of Bat-CoV. The a and d positions of the strongest predicted coiled-coil heptad repeats are indicated. The 14-amino-acid residue insertions that are unique in group 1 viruses are underlined.
