| Short Name | SF1_Hel_unc_tv |
| description | This entry represents an uncharacterised domain found in SF1 helicases from tornidovirus, including Breda virus serotype 1. This group of viruses belong to Nidovirales order and it shares the same genome organisation. It encodes the large polyprotein pp1a which is then proteolytically processed to produce the enzymes required for the replicative machinery. This is a novel cluster of nidoviruses that significantly diverged from toroviruses and, even more, from coronaviruses, roniviruses, and arteriviruses []. This domain connects the zinc-binding domain (ZBD) with the first helicase domain, resembling that of the 1B domain in SARS-Nsp13 helicase [, ]. |
