SwePub titelinformation: Rit1, a tRNA backbone-modifying enzyme that mediates initiator and elongator tRNA discrimination. Överföring RNA (tRNA) är en viktig del av den translationella maskinen i Application to studying recognition of Escherichia coli initiator tRNA Nucleotide sequence of neurospora crassa cytoplasmic initiator trna. Similar to initiator tRNAs from the cytoplasm of other eukaryotes, this tRNA also contains Ett kodon som signalerar initiering av proteintranslation (genetisk translation) genom att stimulera bindning av initierings-tRNA (transfer-RNA, Codon, Initiator. Functions in the early steps of protein synthesis by forming a ternary complex with GTP and initiator tRNA. This complex binds to a 4S ribosomal subunit, Transfer-RNA (av engelskans transfer RNA, förkortat tRNA) är RNA som har till uppgift att transportera aminosyror till ribosomerna i cellen för att användas i The kinetics of initiator transfer RNA (tRNA) interaction with the messenger RNA (mRNA)‐programmed 30S subunit and the rate of 50S subunit docking to the Accuracy of initiator tRNA selection in initiation of eubacterial protein. synthesis.

Initiator trna

Each tRNA contains a set of three nucleotides called an anticodon. What is unusual about the initiator tRNA in prokaryotes? It carries a modified amino acid AND it does not bind to the ribosome at the A site If an aminoacyl-tRNA synthetase added the wrong amino acid to a tRNA, what would happen? The tRNA would carry the wrong amino acid, and it would be incorporated into the growing protein.

Thermodynamic characterization of ppGpp binding to EF-G or IF2 and of initiator tRNA binding to free IF2 in the presence of GDP, GTP, or ppGpp.

The initiator tRNAplays an important role in this process and in the selectionof the appropriate initiation codon. Because of its specialfunction, an initiator tRNA possesses many highly specific properties that are different from those of elongatortRNAs (RajBhandary 1994).
