This enzyme catalyses the following chemical reaction Hydrolyses 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 This enzyme is present in plant RNA viruses of the Potyviridae family. HC-Pro is encoded by all potyviruses, but is absent in some members of the Ipomovirus genus. HC-Pro is involved in virus transmission, virus polyprotein processing, and suppression of RNA silencing, an antiviral mechanism of plants."@en . . . . "3.4"^^ . "3.4.22.45" . . . . . . . "3"^^ .
