Together with the NS5 polymerase, the NS3 helicase has a pivotal function in flavivirus RNA replication and constitutes an important drug target. We captured the dengue virus NS3 helicase at several stages along the catalytic pathway including bound to single-stranded (ss) RNA, to an ATP analogue, to a transition-state analogue and to ATP hydrolysis(More)
We show that the products of SPO1 genes 44, 50, and 51 are required for the normal transition from early to middle gene expression during infection of Bacillus subtilis by bacteriophage SPO1; that they are also required for control of the shutoff of host DNA, RNA, and protein synthesis; and that their effects on host shutoff could be accounted for by their(More)
