The crystal structure of agmatidine tRNA-Ile2 bound to the 70S ribosome in the A and P site.The crystal structure of agmatidine tRNA-Ile2 bound to the 70S ribosome in the A and P site.
Structural highlights
FunctionRS4_THET8 One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it helps nucleate assembly of the body and platform of the 30S subunit. Binds mRNA in the 70S ribosome, positioning it for translation.[HAMAP-Rule:MF_01306_B] Publication Abstract from PubMedDecoding of the AUA isoleucine codon in bacteria and archaea requires modification of a C in the anticodon wobble position of the isoleucine tRNA. Here, we report the crystal structure of the archaeal tRNA2Ile, which contains the modification agmatidine in its anticodon, in complex with the AUA codon on the 70S ribosome. The structure illustrates how agmatidine confers codon specificity for AUA over AUG.
