Selective cleavage of Gln-|-Gly bond in the poliovirus polyprotein. In other picornavirus reactions Glu may be substituted for Gln, and Ser or Thr for Gly.
Autocatalytically cleaves itself from the polyprotein of the foot-and-mouth disease virus by hydrolysis of a Lys-|-Gly bond, but then cleaves host cell initiation factor eIF-4G at bonds -Gly-|-Arg- and -Lys-|-Arg-.

Note, where more than one E.C. class is given (as above), each may
correspond to a different protein domain or, in the case of polyprotein
precursors, to a different mature protein.
