Recognition of the tRNA elbow by tRNA-binding proteins. (A) Structure of LeuRS recognizing its cognate tRNALeu. (PDB ID 2V0G). (B) Structure of ValRS recognizing its cognate tRNAVal. (PDB ID 1GAX). (C) Structure of bacterial amidotransferase GatCAB complexed with GluRS recognizing its cognate tRNAGln. (PDB ID 3AL0). (D) Structure of RNase Z recognizing pre-tRNAThr. (PDB ID 4GCW). (E) Structure of the dihydrouridine synthetase DusC bound to tRNATrp. (PDB ID 4YCP). (F) Model of pseudouridine synthase TruB bound to λ-form tRNAVal based on its cocrystal structure in complex with a tRNA minihelix. (PDB ID 1K8W and 1J2B). (G) Structure of archaeosine transglycosylase ArcTGT bound to λ-form tRNAVal (PDB ID 1J2B).
