Next, AlphaFold2 models for individual Drosophila melanogaster histones were aligned to their 3LZ0 counterparts, and further optimized in the density using rigid-body fit. Then, in Coot, the models were Real-space refined in conjunction with DNA 601 Widom sequence. The DNA sequence was extended, to fit into the density. For the final model optimization, phenix.real_space_refine was used | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
