Table 5 Comparison of the fitted parameters by IDAP, TITAN, and NmrLineGuru for the E22A CsnN174 chitosanase titration data10. The input data for IDAP and NmrLineGuru are the six 1D spectral slices described in Fig. 7 while TITAN uses nine amide NH 2D peaks10 (residues N23, W28, A30, G39, G43, G47, G153, T157, and D232). The fitted values for IDAP and TITAN are from reference10. The fitted parameter values for NmrLineGuru are shown with 95% confidence intervals determined by Monte Carlo resampling. UB: not determined due to reaching the upper boundary (50000 s−1).
