Accession:GO:0036317 term browser browse the term
Definition:Catalysis of the hydrolysis of a 5' tyrosyl-RNA phosphodiester bond between a protein and RNA. In picornaviruses, this covalent bond connects VPg, a viral-encoded protein essential for RNA replication, to the 5' end of all nascent picornavirus genomes; it is cleaved from viral RNA prior to its engaging in protein synthesis.
Synonyms:exact_synonym: VPg unlinkase activity;   Y-pUpN PDE activity;   unlinkase activity;   uridylylpolynucleotide-(5' P->O)- tyrosine phosphodiesterase activity
