構造決定の手法: 単波長異常分散 / 解像度: 2.15→32.46 Å / Rfactor Rfree error: 0.006 / Data cutoff high absF: 51761.57 / Data cutoff low absF: 0 / Isotropic thermal model: RESTRAINED / 交差検証法: THROUGHOUT / σ(F): 0 / 立体化学のターゲット値: Engh & Huber 詳細: Residues listed as missing in Remark 465 are due to lack of electron density. Residues with missing atoms listed in Remark 470 are due to lack of electron density for side chains and modeled as alanines.
