Figure 2. Analysis of eEF2K mutants.
(A) Data for activity and ATP binding (UV cross-linking of [α-32P]ATP) to wild-type GST–eEF2K or the indicated point mutants: data for autophosphorylation of GST–eEF2K or activity against eEF2 are shown as a comparison (the Figure is an autoradiograph of an SDS/PAGE gel); the bottom section shows a Coomassie Brilliant Blue-stained gel of the GST–eEF2K proteins used. (B) Activities of selected point mutants against the MH-1 peptide. All assays were performed within the linear range of the assay. WT, wild-type.
