WebTo address this problem, we present a combined co-crys- tallization and peptide-soaking approach to obtain crystals for any 14-3-3 –peptide complex that may exhibit difﬁculties when crystallizing under our optimized ‘sigma’ conditions. WebAn alternative approach for fragment screening is the co-crystallization of the protein in the presence of the fragment. This method is resource-intensive since each compound requires a separate crystallization experiment. Thus, co-crystallization is commonly used when fragment soaking either affects crystal stability or fails to identify any hits.
