SYRC_HUMAN Forms part of a macromolecular complex that catalyzes the attachment of specific amino acids to cognate tRNAs during protein synthesis. Modulates the secretion of AIMP1 and may be involved in generation of the inflammatory cytokine EMAP2 from AIMP1.[1]
Publication Abstract from PubMed
Arginyl-tRNA synthetase (ArgRS) is a tRNA-binding protein that catalyzes the esterification of l-arginine to its cognate tRNA. l-Canavanine, a structural analog of l-arginine, has recently been studied as an anticancer agent. Here, we determined the crystal structures of the apo, l-arginine-complexed, and l-canavanine-complexed forms of the cytoplasmic free isoform of human ArgRS (hArgRS). Similar interactions were formed upon binding to l-canavanine or l-arginine, but the interaction between Tyr312 and the oxygen of the oxyguanidino group was a little bit different. Detailed conformational changes that occur upon substrate binding were explained. The hArgRS structure was also compared with previously reported homologue structures. The results presented here may provide a basis for the design of new anticancer drugs, such as l-canavanine analogs.
