NMR derived backbone N-H bond vector model-free squared generalized order parameters ( $O_{NH}^2$) for CaM in complex with CaMKKap determined with relaxation data obtained at 500 and 750 MHz (¹H). The error bars, defined by Monte Carlo simulations, are too small to be resolved from the measured value in most cases. Non-proline residues with no entry were not determined due to spectral overlap.
