Figure Lengend Snippet: a Strep-tag pull-down assay demonstrating interaction of ICP8 with either full-length UL9 or UL9CTD. b GST pull-down assay analyzing binding between ICP8 and either UL9CTD or the C-tail. c Comparative ATPase activity of wild-type UL9 versus its functional mutants. ATPase activity assays were performed using the Malachite Green Phosphate Detection Kit. Data are presented as the mean with standard deviation for experiments performed in triplicate. Statistical significance was determined by a two-tailed Student’s t -test (*p < 0.05, **p < 0.01, *p < 0.001). d ICP8-mediated stimulation of UL9 helicase activity. Wild-type UL9 and two C-terminal truncation mutants (ΔC16 and ΔC8) were tested.
Article Snippet: UL9 CTD and its truncation mutants used for GST pull-down assays, along with two C-tail fragments, were cloned into the pGEX-6P-1 vector (GE Healthcare) to generate GST-tagged fusion proteins.
