Journal: Mol Cell / Year: 2025 Title: Mechanism of cotranslational protein N-myristoylation in human cells. Authors: Martin Gamerdinger / Blanca Echeverria / Alfred M Lentzsch / Nicolas Burg / Ziyi Fan / Mateusz Jaskolowski / Alain Scaiola / Selina Piening / Shu-Ou Shan / Nenad Ban / Elke Deuerling / Abstract: N-myristoyltransferases (NMTs) cotranslationally transfer the fatty acid myristic acid to the N terminus of newly synthesized proteins, regulating their function and cellular localization. These ...N-myristoyltransferases (NMTs) cotranslationally transfer the fatty acid myristic acid to the N terminus of newly synthesized proteins, regulating their function and cellular localization. These enzymes are important drug targets for the treatment of cancer and viral infections. N-myristoylation of nascent proteins occurs specifically on N-terminal glycine residues after the excision of the initiator methionine by methionine aminopeptidases (METAPs). How NMTs interact with ribosomes and gain timely and specific access to their substrates remains unknown. Here, we show that human NMT1 exchanges with METAP1 at the ribosomal tunnel exit to form an active cotranslational complex together with the nascent polypeptide-associated complex (NAC). NMT1 binding is sequence selective and specifically triggered by methionine excision, which exposes the N-myristoylation motif in the nascent chain. The revealed mode of interaction of NMT1 with NAC and the methionine-cleaved nascent protein elucidates how a specific subset of proteins can be efficiently N-myristoylated in human cells.
In the structure databanks used in Yorodumi, some data are registered as the other names, "COVID-19 virus" and "2019-nCoV". Here are the details of the virus and the list of structure data.
Jan 31, 2019. EMDB accession codes are about to change! (news from PDBe EMDB page)
EMDB accession codes are about to change! (news from PDBe EMDB page)
The allocation of 4 digits for EMDB accession codes will soon come to an end. Whilst these codes will remain in use, new EMDB accession codes will include an additional digit and will expand incrementally as the available range of codes is exhausted. The current 4-digit format prefixed with “EMD-” (i.e. EMD-XXXX) will advance to a 5-digit format (i.e. EMD-XXXXX), and so on. It is currently estimated that the 4-digit codes will be depleted around Spring 2019, at which point the 5-digit format will come into force.
The EM Navigator/Yorodumi systems omit the EMD- prefix.

Yorodumi is a browser for structure data from EMDB, PDB, SASBDB, etc.
This page is also the successor to EM Navigator detail page, and also detail information page/front-end page for Omokage search.
The word "yorodu" (or yorozu) is an old Japanese word meaning "ten thousand". "mi" (miru) is to see.
