Function

[R1A_PEDV7] The papain-like proteinase 1 (PLP1) and papain-like proteinase 2 (PLP2) are responsible for the cleavages located at the N-terminus of the replicase polyprotein. In addition, PLP2 possesses a deubiquitinating/deISGylating activity and processes both 'Lys-48'- and 'Lys-63'-linked polyubiquitin chains from cellular substrates. PLP2 also antagonizes innate immune induction of type I interferon by blocking the nuclear translocation of host IRF-3 (By similarity). The main proteinase 3CL-PRO is responsible for the majority of cleavages as it cleaves the C-terminus of replicase polyprotein at 11 sites. Recognizes substrates containing the core sequence [ILMVF]-Q-|-[SGACN]. Inhibited by the substrate-analog Cbz-Val-Asn-Ser-Thr-Leu-Gln-CMK. Also contains an ADP-ribose-1-phosphate (ADRP)-binding function (By similarity).[PROSITE-ProRule:PRU00772] Nsp7-nsp8 hexadecamer may possibly confer processivity to the polymerase, maybe by binding to dsRNA or by producing primers utilized by the latter. Nsp9 is a ssRNA-binding protein.

Publication Abstract from PubMed

Porcine epidemic diarrhea virus (PEDV) causes high mortality in pigs. PEDV main protease (Mpro) plays an essential role in viral replication. We solved the structure of PEDV Mpro complexed with peptidomimetic inhibitor N3 carrying a Michael acceptor warhead, revealing atomic level interactions. We further designed a series of 17 inhibitors with altered side groups. Inhibitors M2 and M17 demonstrated enhanced specificity against PEDV Mpro. These compounds have potential as future therapeutics to combat PEDV infection.
