“Science is not about building a body of known ‘facts’.

It is a method for asking awkward questions and subjecting them to a reality-check, thus avoiding the human tendency to believe whatever makes us feel good.”

Hexamerization has been proposed to be required for optimal enzyme activity, most probably by stabilizing the catalytic site in its active conformation 17 and

(A) Northern blot analysis of genome (RNA1) and sg mRNA (RNAs 2 to 7) synthesis in BHK-21 cells transfected with EAv nsp1 ZF mutants (14 hpt) and the RNAko mutant designed to

Previous studies of the role of nsp1 in the EAv replicative cycle focused on the conserved amino acids presumed to be essential either for zinc binding by the ZF domain or for

Wild-type nsp1-HN-ap could be efficiently purified by metal affinity chromatography with Talon resin (charged with cobalt ions), albeit in the presence of a number of abun-

This approach was em- ployed in the research outlined in Chapters 3 and 4 to gain more insight into the role of the conserved NendoU domain in the EAv replicative cycle and to

These data identified nsp1 as a multifunctional replicase subunit with critical functions in at least three consecutive key processes in the EAv replicative cycle:

De autoproteolytische klieving van nsp1 van de replicase polyproteïnen wordt uitgevoerd door een C-terminaal papaine-achtig cysteine proteinase domein (PCPβ), en klieving tussen
