Identification of novel cellular proteins as substrates to viral proteases would provide a new insight into the mechanism of cell-virus interplay. Eight nuclear proteins as potential targets for enterovirus 71 (EV71) 3C protease (3C(pro)) cleavages were identified by 2D electrophoresis and MALDI-TOF analysis. Of these proteins, CstF-64, which is a critical factor for 3' pre-mRNA processing in a...
Foot-and-mouth disease virus (FMDV) is a significant economically and distributed globally pathogen of Artiodactyla. Current vaccines are chemically inactivated whole virus particles that require large-scale virus growth in strict bio-containment with the associated risks of accidental release or incomplete inactivation. Non-infectious empty capsids are structural mimics of authentic particles ...
We have developed a simple in vitro translation method to analyze compounds that inhibit the rhinovirus 3C protease in peptide substrate assays but demonstrate no antiviral activity. This complementary assay, which provides both qualitative and quantitative results, detects the inhibition of the 3CD protease in the native polyprotein form.
The human rhinovirus 14 3C protease (HRV3C protease), in fusion with glutathione S-transferase also referred to as PreScission™ protease, is a cysteine of particular interest for affinity tag removal from proteins due its stringent recognition sequence specificity (LEVLFQ/GX) and superior activity at low temperature. Here we report the expression, purification use construct HRV3C NT*-HRV3CP, th...
We have previously shown that poliovirus (PV) infection induces stress granule (SG) formation early in infection and then inhibits the formation of SG and disperses processing bodies (PBs) by the mid-phase of infection. Loss of SG was linked to cleavage of G3BP1 by viral 3C proteinase (3C(pro)), however dispersal of PBs was not strongly linked to cleavage of specific factors by viral proteinase...
Highly conserved configuration of catalytic amino acid residues among calicivirus-encoded proteases.
A common feature of caliciviruses is the proteolytic processing of the viral polyprotein catalyzed by the viral 3C-like protease encoded in open reading frame 1 (ORF1). Here we report the identification and structural characterization of the protease domains and amino acid residues in sapovirus (SaV) and feline calicivirus (FCV). The in vitro expression and processing of a panel of truncated OR...
Infection of cells by foot-and-mouth disease virus (FMDV) results in the rapid inhibition of host cell protein synthesis. This process is accompanied by the early cleavage of the translation initiation factor eIF4G, a component of the cap-binding complex eIF4F. This cleavage is mediated by the leader (L) protease. Subsequently, as the virus proteins accumulate, secondary cleavages of eIF4G occu...
Expression studies conducted in vitro and in Escherichia coli led to the identification of a protease from rabbit hemorrhagic disease virus (RHDV). The gene coding for this protease was found to be located in the central part of the genome preceding the putative RNA polymerase gene. It was demonstrated that the protease specifically cuts RHDV polyprotein substrates both in cis and in trans. Sit...
