*Amino acid identities for the open reading frame (ORF), capsid region (P1), and nonstructural region (P2-P3) are based on p-distance models between K251176-02 (DQ315670) and the HPeV prototypes, HPeV1 (H) (Harris, S45208), HPeV2 (W) (Williamson, AJ005695), HPeV2 (CT) (CT86-6760, AF055846), HPeV3 (A308) (A308-99, AB084913), and HPeV3 (Can) (Can82853-01, AJ889918). The full-length sequence of K251176-02 was aligned with the HPeV prototypes by using ClustalW, included in the Vector NTI Advance 10 software package (Invitrogen, Carlsbad, CA, USA). Alignment was edited by using GeneDoc software (version 2.6.02). The matrix was constructed by using MEGA version 3.1. The 5´ untranslated region (UTR) and 3´ UTR are excluded from the analysis because the regions are noncoding. | |
