The 90S pre-ribosome is an early biogenesis intermediate formed during co-transcriptional ribosome formation, composed of ∼70 assembly factors and several small nucleolar RNAs (snoRNAs) that associate with nascent pre-rRNA. We report the cryo-EM structure of the Chaetomium thermophilum 90S pre-ribosome, revealing how a network of biogenesis factors including 19 β-propellers and large α-solenoid proteins engulfs the pre-rRNA. Within the 90S pre-ribosome, we identify the UTP-A, UTP-B, Mpp10-Imp3-Imp4, Bms1-Rcl1, and U3 snoRNP modules, which are organized around 5'-ETS and partially folded 18S rRNA. The U3 snoRNP is strategically positioned at the center of the 90S particle to perform its multiple tasks during pre-rRNA folding and processing. The architecture of the elusive 90S pre-ribosome gives unprecedented structural insight into the early steps of pre-rRNA maturation. Nascent rRNA that is co-transcriptionally folded and given a particular shape by encapsulation within a dedicated mold-like structure is reminiscent of how polypeptides use chaperone chambers for their protein folding. 履歴 登録 2016年5月4日 登録サイト : RCSB / 処理サイト : PDBE改定 1.0 2016年7月27日 Provider : repository / タイプ : Initial release改定 1.1 2016年8月3日 Group : Other改定 1.2 2017年7月5日 Group : Structure summary / カテゴリ : entity / Item : _entity.pdbx_description改定 1.3 2018年10月24日 Group : Advisory / Data collection / Derived calculationsカテゴリ : em_image_scans / ndb_struct_na_base_pair ... em_image_scans / ndb_struct_na_base_pair / ndb_struct_na_base_pair_step / pdbx_unobs_or_zero_occ_atoms / pdbx_validate_close_contact / struct_conn 改定 1.4 2018年11月21日 Group : Advisory / Data collection / Derived calculationsカテゴリ : pdbx_unobs_or_zero_occ_atoms / pdbx_validate_close_contact / struct_conn改定 1.5 2019年1月23日 Group : Advisory / Data collection / Derived calculationsカテゴリ : pdbx_unobs_or_zero_occ_atoms / pdbx_validate_close_contact ... pdbx_unobs_or_zero_occ_atoms / pdbx_validate_close_contact / struct_conn / struct_conn_type 改定 1.6 2020年3月11日 Group : Source and taxonomy / カテゴリ : entity_src_nat / Item : _entity_src_nat.pdbx_ncbi_taxonomy_id改定 1.7 2024年5月8日 Group : Data collection / Database references / カテゴリ : chem_comp_atom / chem_comp_bond / database_2Item : _database_2.pdbx_DOI / _database_2.pdbx_database_accession
