CS-Rosetta-AbinitioRelax, CS-Rosetta-FloppyTail The structure of the core regions of H2A(Val27-Leu96) and H2B (Ser38-Lys125) connected by a random coil (Gly)16 poly-glycine linker was modeled by CS-Rosetta-AbinitioRelax protocol.In total 10,000 models were generated and selected the 10 models with the lowest CA-RMSD from the 20 models with the lowest CS-Rosetta energy., After the (Gly)16 poly-glycine linker was removed from each of the 10 selected structures of the H2A-H2B core, the flexible tails of H2A (Gly(-3)-Pro26 and Leu97-Lys129) and H2B (Gly(-3)-Tyr37) were connected by using MODELLER program. Next, for each of the three flexible tails,CS-Rosetta-FloppyTail protocol was used to generate 10,000 models for each of the 10 selected core structures, and selected one model with the lowest kai2 values of chemical shifts. 1
