Function
POLG_NVN68 Protein p48 may play a role in viral replication by interacting with host VAPA, a vesicle-associated membrane protein that plays a role in SNARE-mediated vesicle fusion. This interaction may target replication complex to intracellular membranes.[1] [2] NTPase presumably plays a role in replication. Despite having similarities with helicases, does not seem to display any helicase activity.[3] [4] Protein P22 may play a role in targeting replication complex to intracellular membranes.[5] [6] Viral genome-linked protein is covalently linked to the 5'-end of the positive-strand, negative-strand genomic RNAs and subgenomic RNA. Acts as a genome-linked replication primer. May recruit ribosome to viral RNA thereby promoting viral proteins translation.[7] [8] 3C-like protease processes the polyprotein: 3CLpro-RdRp is first released by autocleavage, then all other proteins are cleaved. May cleave host polyadenylate-binding protein thereby inhibiting cellular translation (By similarity).[9] [10] RNA-directed RNA polymerase replicates genomic and antigenomic RNA by recognizing replications specific signals. Transcribes also a subgenomic mRNA by initiating RNA synthesis internally on antigenomic RNA. This sgRNA encodes for structural proteins. Catalyzes the covalent attachment VPg with viral RNAs (By similarity).[11] [12]
Publication Abstract from PubMed
Acute nonbacterial gastroenteritis caused by noroviruses constitutes a global public health concern and a significant economic burden. There are currently no small molecule therapeutics or vaccines for the treatment of norovirus infections. A structure-guided approach was utilized in the design of a series of inhibitors of norovirus 3CL protease that embody an oxazolidinone ring as a novel design element for attaining optimal binding interactions. Low micromolar cell-permeable inhibitors that display anti-norovirus activity have been identified. The mechanism of action, mode of binding, and structural rearrangements associated with the interaction of the inhibitors and the enzyme were elucidated using X-ray crystallography.
