引用ジャーナル : ACS Nano / 年 : 2021タイトル : Affinity Capture of p97 with Small-Molecule Ligand Bait Reveals a 3.6 Å Double-Hexamer Cryoelectron Microscopy Structure.著者 : Md Rejaul Hoq / Frank S Vago / Kunpeng Li / Marina Kovaliov / Robert J Nicholas / Donna M Huryn / Peter Wipf / Wen Jiang / David H Thompson / 要旨 : Recent progress in the development of affinity grids for cryoelectron microscopy (cryo-EM) typically employs genetic engineering of the protein sample such as histidine or Spy tagging, immobilized ... Recent progress in the development of affinity grids for cryoelectron microscopy (cryo-EM) typically employs genetic engineering of the protein sample such as histidine or Spy tagging, immobilized antibody capture, or nonselective immobilization via electrostatic interactions or Schiff base formation. We report a powerful and flexible method for the affinity capture of target proteins for cryo-EM analysis that utilizes small-molecule ligands as bait for concentrating human target proteins directly onto the grid surface for single-particle reconstruction. This approach is demonstrated for human p97, captured using two different small-molecule high-affinity ligands of this AAA+ ATPase. Four electron density maps are revealed, each representing a p97 conformational state captured from solution, including a double-hexamer structure resolved to 3.6 Å. These results demonstrate that the noncovalent capture of protein targets on EM grids modified with high-affinity ligands can enable the structure elucidation of multiple configurational states of the target and potentially inform structure-based drug design campaigns. 履歴 登録 2021年5月3日 - ヘッダ(付随情報) 公開 2021年6月2日 - マップ公開 2021年6月2日 - 更新 2021年6月9日 - 現状 2021年6月9日 処理サイト : RCSB / 状態 : 公開
