Superfamily: nsp15 middle domain

The unique coronavirus transcription/replication machinery comprised of multiple virus-encoded nonstructural proteins (nsp) plays a vital role during initial and intermediate phases of the viral life cycle.

nsp15 forms a hexamer which is suggested to be a functional unit. It also has endoribonuclease activity. The nsp15 monomer consists of three domains. This entry represents the middle domain which is made up of a major mixed beta-sheet, three small ones and two short alpha-helices PMID:16873248.
