CC   -!- FUNCTION: [Nuclear inclusion protein A]: Has RNA-binding and
CC       proteolytic activities. {ECO:0000250|UniProtKB:P04517}.
CC   -!- FUNCTION: [Nuclear inclusion protein B]: An RNA-dependent RNA
CC       polymerase that plays an essential role in the virus replication.
CC   -!- FUNCTION: [Capsid protein]: Involved in aphid transmission, cell-to-
CC       cell and systemis movement, encapsidation of the viral RNA and in the
CC       regulation of viral RNA amplification. {ECO:0000250|UniProtKB:P04517}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Hydrolyzes glutaminyl bonds, and activity is further
CC         restricted by preferences for the amino acids in P6 - P1' that vary
CC         with the species of potyvirus, e.g. Glu-Xaa-Xaa-Tyr-Xaa-Gln-|-(Ser or
CC         Gly) for the enzyme from tobacco etch virus. The natural substrate is
CC         the viral polyprotein, but other proteins and oligopeptides
CC         containing the appropriate consensus sequence are also cleaved.;
CC         EC=3.4.22.44; Evidence={ECO:0000250|UniProtKB:P04517};
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a ribonucleoside 5'-triphosphate + RNA(n) = diphosphate +
CC         RNA(n+1); Xref=Rhea:RHEA:21248, Rhea:RHEA-COMP:14527, Rhea:RHEA-
CC         COMP:17342, ChEBI:CHEBI:33019, ChEBI:CHEBI:61557, ChEBI:CHEBI:140395;
CC         EC=2.7.7.48; Evidence={ECO:0000255|PROSITE-ProRule:PRU00539};
CC   -!- SUBCELLULAR LOCATION: [Capsid protein]: Virion {ECO:0000305}.
CC   -!- PTM: Genome polyprotein of potyviruses undergoes post-translational
CC       proteolytic processing by the main proteinase NIa-pro resulting in the
CC       production of at least ten individual proteins. The P1 proteinase and
CC       the HC-pro cleave only their respective C-termini autocatalytically.
CC       6K1 is essential for proper proteolytic separation of P3 from CI (By
CC       similarity). {ECO:0000250}.
CC   -!- BIOTECHNOLOGY: The gene for the coat protein is introduced by genetic
CC       manipulation and expressed in squash so as to obtain virus resistant
CC       plants.
CC   -!- MISCELLANEOUS: Readthrough of a terminator codon TGA occurs between
CC       codons for Ala-267 and Gln-269.
CC   -!- SIMILARITY: Belongs to the potyviridae genome polyprotein family.
CC       {ECO:0000305}.
