(a) Determination of qthreshold (see text for details) for reliable coarse-grained calculation of protein X-ray scattering for hen egg-white lysozyme (PDB code 6lyz) and carbonmonoxy hemoglobin (PDB code 2hhb). The cofactors were removed before evaluating the scattering. (b) For each structure of the protein structure library, the maximum q value with an error lower than 0.2% [according to equation (12)] was determined. The histogram illustrates the distribution of these qthreshold values for both coarse-grained methods (amino acid and MARTINI). |
