Function

[A9XG43_9ENTO] Protein 2C associates with and induces structural rearrangements of intracellular membranes. It displays RNA-binding, nucleotide binding and NTPase activities (By similarity).[SAAS:SAAS000199_004_016611] Protein 3C is a cysteine protease that generates mature viral proteins from the precursor polyprotein. In addition to its proteolytic activity, it binds to viral RNA, and thus influences viral genome replication. RNA and substrate bind co-operatively to the protease (By similarity).[SAAS:SAAS000199_004_042266] RNA-directed RNA polymerase 3D-POL replicates genomic and antigenomic RNA by recognizing replications specific signals (By similarity).[SAAS:SAAS000199_004_010047]

Publication Abstract from PubMed

Enterovirus 71 (EV71) is the causative agent of hand, foot and mouth disease and can spread its infections to the central nervous and other systems with severe consequences. The replication of EV71 depends on its 3C proteinase (3Cpro ), a significant drug target. By X-ray crystallography and functional assays, the interactions between inhibitors and EV71 3Cpro were evaluated. It was shown that improved interactions at S4 for the substrate binding could significantly enhance the potency. A new series of potent inhibitors with high ligand efficiency was generated for developing antivirals to treat and control the EV71-associated diseases. Copyright (c) 2016 John Wiley & Sons, Ltd.
