WebJan 30, 2008 · Even when pure soluble protein is available, producing high-quality crystals is another bottleneck for structure determination because crystallization is a complex, multiparametric process. WebThe crystallization pH for the vast majority of protein complexes was between 5.0 and 8.0. Overall, the boundaries for the crystallization configuration space of protein complexes appear to be more restricted than those of soluble proteins. This may reflect the limited stability and solubility of protein-protein complexes.
