Before they can function as signaling molecules, Hedgehog precursor proteins must undergo amino-terminal palmitoylation by Hedgehog acyltransferase (HHAT). We present cryo-electron microscopy structures of human HHAT in complex with its palmitoyl-coenzyme A substrate and of a product complex with a palmitoylated Hedgehog peptide at resolutions of 2.7 and 3.2 angstroms, respectively. The structures reveal how HHAT overcomes the challenges of bringing together substrates that have different physiochemical properties from opposite sides of the endoplasmic reticulum membrane within a membrane-embedded active site for catalysis. These principles are relevant to related enzymes that catalyze the acylation of Wnt and of the appetite-stimulating hormone ghrelin. The structural and mechanistic insights may advance the development of inhibitors for cancer. 履歴 登録 2021年4月16日 登録サイト : RCSB / 処理サイト : RCSB改定 1.0 2021年6月16日 Provider : repository / タイプ : Initial release改定 1.1 2021年7月14日 Group : Database references / カテゴリ : citationItem : _citation.journal_volume / _citation.page_first ... _citation.journal_volume / _citation.page_first / _citation.page_last / _citation.pdbx_database_id_PubMed / _citation.title 改定 2.0 2021年8月25日 Group : Advisory / Atomic model ...
