Sequence alignment of various type 2 coronaviral PLpros. Group 1, HCoV229E; group 2a, BCoV and HCoV-HKU1; group 2b, SARS-CoV and MERS-CoV; group 3, IBV. The blue and green ovals indicate residues making polar contact with the Ub core and C-terminus, respectively, while the magenta ovals indicate the catalytic triad. The red boxes with white characters indicate residues with strict identity, while blue boxes with red characters show residues with similarity in a group. Accession numbers are as follows: SARS-CoV, AY291451; MERS-CoV, NC019843.2; BCoV, NC012948.1; HCoV-HKU1, DQ415909.1; HCoV-229E, JX503060.1; IBV, JQ088078.1. |
