A fuzzy charge–charge interaction enhances PP1α C-tail binding to ASPP2. a Fully annotated 2D [1H,15N] HSQC of PP1301-330. b 2D [1H,15N] HSQC of PP1301-330 (black) in presence of a 2 (violet) or 4 (green) molar excess of ASPP2. c Comparative analysis of 15N[1H] NOE of free PP1α C-tail (black bars) and PP1α C-tail: ASPP2 (grey bars); missing peaks are due to overlap, making quantitative intensity analysis impossible. Error bars represent standard deviations. d Comparative analysis of 15N transverse relaxation (R2) data of free PP1α C-tail (black bars) and PP1α C-tail: ASPP2 (grey bars). Error bars represent standard deviations
