Here, we report a mechanism for SARS-CoV-2 RNA capping and document structural details at atomic resolution. The NiRAN domain in polymerase catalyzes the covalent link of RNA 5' end to the first residue of nsp9 (termed as RNAylation), thus being an intermediate to form cap core (GpppA) with GTP catalyzed again by NiRAN. We also reveal that triphosphorylated nucleotide analog inhibitors can be bonded to nsp9 and fit into a previously unknown "Nuc-pocket" in NiRAN, thus inhibiting nsp9 RNAylation and formation of GpppA. S-loop (residues 50-KTN-52) in NiRAN presents a remarkable conformational shift observed in RTC bound with sofosbuvir monophosphate, reasoning an "induce-and-lock" mechanism to design inhibitors. These findings not only improve the understanding of SARS-CoV-2 RNA capping and the mode of action of NAIs but also provide a strategy to design antiviral drugs. 履歴 登録 2022年9月17日 登録サイト : PDBJ / 処理サイト : PDBJ改定 1.0 2022年12月14日 Provider : repository / タイプ : Initial release改定 1.0 2022年12月14日 Data content type : EM metadata / Data content type : EM metadata / Provider : repository / タイプ : Initial release改定 1.0 2022年12月14日 Data content type : Half map / Part number : 1 / Data content type : Half map / Provider : repository / タイプ : Initial release改定 1.0 2022年12月14日 Data content type : Half map / Part number : 2 / Data content type : Half map / Provider : repository / タイプ : Initial release改定 1.0 2022年12月14日 Data content type : Image / Data content type : Image / Provider : repository / タイプ : Initial release改定 1.0 2022年12月14日 Data content type : Primary map / Data content type : Primary map / Provider : repository / タイプ : Initial release改定 1.0 2022年12月14日 Data content type : Half map / Part number : 1 / Data content type : Half map / Provider : repository / タイプ : Initial release改定 1.0 2022年12月14日 Data content type : Half map / Part number : 2 / Data content type : Half map / Provider : repository / タイプ : Initial release改定 1.0 2022年12月14日 Data content type : Image / Data content type : Image / Provider : repository / タイプ : Initial release改定 1.0 2022年12月14日 Data content type : Primary map / Data content type : Primary map / Provider : repository / タイプ : Initial release改定 1.1 2024年7月3日 Group : Data collection / カテゴリ : chem_comp_atom / chem_comp_bond / em_admin / Item : _em_admin.last_update改定 2.0 2025年4月9日 Group : Advisory / Atomic model ...
