Turnip mosaic virus (strain Quebec) (TuMV)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Capsid protein: involved in aphid transmission, cell-to-cell and systemis movement, encapsidation of the viral RNA and in the regulation of viral RNA amplification.
Nuclear inclusion protein B: an RNA-dependent RNA polymerase that plays an essential role in the virus replication.
Helper component proteinase: required for aphid transmission and also has proteolytic activity. Only cleaves a Gly-Gly dipeptide at its own C-terminus. Interacts with virions and aphid stylets. Acts as a suppressor of RNA-mediated gene silencing, also known as post-transcriptional gene silencing (PTGS), a mechanism of plant viral defense that limits the accumulation of viral RNAs. May have RNA-binding activity (By similarity).By similarity
Cytoplasmic inclusion protein: has helicase activity. It may be involved in replication (By similarity).By similarity
Both 6K peptides are indispensable for virus replication.By similarity
Nuclear inclusion protein A: has RNA-binding and proteolytic activities.

Catalytic activityi

Hydrolyzes glutaminyl bonds, and activity is further restricted by preferences for the amino acids in P6 - P1' that vary with the species of potyvirus, e.g. Glu-Xaa-Xaa-Tyr-Xaa-Gln-|-(Ser or Gly) for the enzyme from tobacco etch virus. The natural substrate is the viral polyprotein, but other proteins and oligopeptides containing the appropriate consensus sequence are also cleaved.
Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1).PROSITE-ProRule annotation
Hydrolyzes a Gly-|-Gly bond at its own C-terminus, commonly in the sequence -Tyr-Xaa-Val-Gly-|-Gly, in the processing of the potyviral polyprotein.

Post-translational modificationi

VPg is uridylylated by the polymerase and is covalently attached to the 5'-end of the genomic RNA. This uridylylated form acts as a nucleotide-peptide primer for the polymerase (By similarity).By similarity
Potyviral RNA is expressed as two polyproteins which undergo post-translational proteolytic processing. Genome polyprotein is processed by NIa-pro, P1 and HC-pro proteinases resulting in the production of at least ten individual proteins. P3N-PIPO polyprotein is cleaved by P1 and HC-pro proteinases resulting in the production of three individual proteins. The P1 proteinase and the HC-pro cleave only their respective C-termini autocatalytically. 6K1 is essential for proper proteolytic separation of P3 from CI (By similarity).By similarity

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
