引用ジャーナル : Mol Cell / 年 : 2024タイトル : Stabilization of the hexasome intermediate during histone exchange by yeast SWR1 complex.著者 : Adam S B Jalal / Paul Girvan / Eugene Y D Chua / Lexin Liu / Shijie Wang / Elizabeth A McCormack / Michael T Skehan / Carol L Knight / David S Rueda / Dale B Wigley / 要旨 : The yeast SWR1 complex catalyzes the exchange of histone H2A/H2B dimers in nucleosomes with Htz1/H2B dimers. We use cryoelectron microscopy to determine the structure of an enzyme-bound hexasome ... The yeast SWR1 complex catalyzes the exchange of histone H2A/H2B dimers in nucleosomes with Htz1/H2B dimers. We use cryoelectron microscopy to determine the structure of an enzyme-bound hexasome intermediate in the reaction pathway of histone exchange, in which an H2A/H2B dimer has been extracted from a nucleosome prior to the insertion of a dimer comprising Htz1/H2B. The structure reveals a key role for the Swc5 subunit in stabilizing the unwrapping of DNA from the histone core of the hexasome. By engineering a crosslink between an Htz1/H2B dimer and its chaperone protein Chz1, we show that this blocks histone exchange by SWR1 but allows the incoming chaperone-dimer complex to insert into the hexasome. We use this reagent to trap an SWR1/hexasome complex with an incoming Htz1/H2B dimer that shows how the reaction progresses to the next step. Taken together the structures reveal insights into the mechanism of histone exchange by SWR1 complex. 履歴 登録 2023年10月26日 - ヘッダ(付随情報) 公開 2024年10月2日 - マップ公開 2024年10月2日 - 更新 2024年10月30日 - 現状 2024年10月30日 処理サイト : PDBe / 状態 : 公開
