CC -!- FUNCTION: [Helper component proteinase]: Required for aphid
CC transmission and also has proteolytic activity. Only cleaves a Gly-Gly
CC dipeptide at its own C-terminus. Interacts with virions and aphid
CC stylets. Acts as a suppressor of RNA-mediated gene silencing, also
CC known as post-transcriptional gene silencing (PTGS), a mechanism of
CC plant viral defense that limits the accumulation of viral RNAs. May
CC have RNA-binding activity. {ECO:0000250|UniProtKB:P04517}.
CC -!- FUNCTION: [Cytoplasmic inclusion protein]: Has helicase activity. It
CC may be involved in replication.
CC -!- FUNCTION: [6 kDa protein 1]: Indispensable for virus replication.
CC {ECO:0000250|UniProtKB:P13529}.
CC -!- FUNCTION: [6 kDa protein 2]: Indispensable for virus replication.
CC {ECO:0000250|UniProtKB:P09814}.
CC -!- FUNCTION: [Viral genome-linked protein]: Mediates the cap-independent,
CC EIF4E-dependent translation of viral genomic RNAs (By similarity).
CC Binds to the cap-binding site of host EIF4E and thus interferes with
CC the host EIF4E-dependent mRNA export and translation (By similarity).
CC VPg-RNA directly binds EIF4E and is a template for transcription (By
CC similarity). Also forms trimeric complexes with EIF4E-EIF4G, which are
CC templates for translation (By similarity).
CC {ECO:0000250|UniProtKB:P18247}.
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=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 -!- 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=Hydrolyzes a Gly-|-Gly bond at its own C-terminus, commonly in
CC the sequence -Tyr-Xaa-Val-Gly-|-Gly, in the processing of the
CC potyviral polyprotein.; EC=3.4.22.45;
CC Evidence={ECO:0000250|UniProtKB:P04517};
CC -!- SUBCELLULAR LOCATION: [6 kDa protein 1]: Host cytoplasmic vesicle.
CC Note=Probably colocalizes with 6K2-induced vesicles associated with
CC host chloroplasts. {ECO:0000250|UniProtKB:P13529}.
CC -!- SUBCELLULAR LOCATION: [6 kDa protein 2]: Host cytoplasmic vesicle
CC {ECO:0000250|UniProtKB:P09814}. Note=6K-induced vesicles associate with
CC host chloroplasts. {ECO:0000250|UniProtKB:P09814}.
CC -!- SUBCELLULAR LOCATION: [Capsid protein]: Virion {ECO:0000305}.
CC -!- DOMAIN: [Helper component proteinase]: The N-terminus is involved in
CC interaction with stylets. The central part is involved in interaction
CC with virions and the C-terminus is involved in cell-to cell movement of
CC the virus.
CC -!- PTM: [Viral genome-linked protein]: VPg is uridylylated by the
CC polymerase and is covalently attached to the 5'-end of the genomic RNA.
CC This uridylylated form acts as a nucleotide-peptide primer for the
CC polymerase (By similarity). {ECO:0000250|UniProtKB:P09814}.
CC -!- PTM: [Genome polyprotein]: Genome polyprotein of potyviruses undergoes
CC post-translational proteolytic processing by the main proteinase NIa-
CC pro resulting in the production of at least ten individual proteins.
CC The P1 proteinase and the HC-pro cleave only their respective C-termini
CC autocatalytically. 6K1 is essential for proper proteolytic separation
CC of P3 from CI (By similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the potyviridae genome polyprotein family.
CC {ECO:0000305}.
