引用ジャーナル : Nat Commun / 年 : 2022タイトル : Structural basis for gating mechanism of the human sodium-potassium pump.著者 : Phong T Nguyen / Christine Deisl / Michael Fine / Trevor S Tippetts / Emiko Uchikawa / Xiao-Chen Bai / Beth Levine / 要旨 : P2-type ATPase sodium-potassium pumps (Na/K-ATPases) are ion-transporting enzymes that use ATP to transport Na and K on opposite sides of the lipid bilayer against their electrochemical gradients to ... P2-type ATPase sodium-potassium pumps (Na/K-ATPases) are ion-transporting enzymes that use ATP to transport Na and K on opposite sides of the lipid bilayer against their electrochemical gradients to maintain ion concentration gradients across the membranes in all animal cells. Despite the available molecular architecture of the Na/K-ATPases, a complete molecular mechanism by which the Na and K ions access into and are released from the pump remains unknown. Here we report five cryo-electron microscopy (cryo-EM) structures of the human alpha3 Na/K-ATPase in its cytoplasmic side-open (E1), ATP-bound cytoplasmic side-open (E1•ATP), ADP-AlF trapped Na-occluded (E1•P-ADP), BeF trapped exoplasmic side-open (E2P) and MgF trapped K-occluded (E2•P) states. Our work reveals the atomically resolved structural detail of the cytoplasmic gating mechanism of the Na/K-ATPase. 履歴 登録 2022年6月1日 - ヘッダ(付随情報) 公開 2022年9月21日 - マップ公開 2022年9月21日 - 更新 2024年11月13日 - 現状 2024年11月13日 処理サイト : RCSB / 状態 : 公開
