SAXS on SpyCatcher003-SpyTag003. (a) Pair distribution functions, area-normalized by molecular weight, and (b) SAXS curves (offset) and residuals of the SpyCatcher003–SpyTag003-sfGFP complex (blue), SpyTag003-sfGFP (green) and SpyCatcher003 (red). The gray curve indicates the fit by the FoXS of the AlphaFold prediction of the complex. Black curves indicate the fits by FoXS from BilboMD-fitted models. (c) Comparison of the crystallography complex (PDB entry 4mli) with the AlphaFold prediction. (d)–(f) Best fit conformations of (d) SpyCatcher003–SpyTag003-sfGFP complex, 2-state ensemble; (e) SpyTag003-sfGFP, 1-state ensemble; and (f) SpyCatcher003, 1-state ensemble, after BilboMD fitting.
