Ampiviruses have rather large protease and polymerase proteins compared to those of other picornaviruses.
No virus has been isolated.
Length of genome (Reuter et al., 2015): 9,246 nt (5'-UTR: 970 nt; ORF: 8,142 nt; 3'-UTR: 134 nt). The location of the cre has not been identified.
Genome layout: VPg+5'UTRIRES[1AB-1C-1D/2A-2B-2C/3A-3B-3C-3D]3'UTR-poly(A)
The deduced polyprotein has a length of 2,713 amino acids. There is no L protein. The function of 2A is unknown.
Viral RNA was detected in faeces of apparently healthy common newts (Lissotriton vulgaris).
Ampi-: from amphibian picornavirus
