None.

Description

Aminoacyl-tRNA synthetases (aaRSs) play a crucial role in the translation of the genetic code by means of covalent attachment of amino acids to their cognate tRNAs. Phenylalanine-tRNA synthetase (PheRS, also known as Phenylalanine-tRNA ligase) is known to be among the most complex enzymes of the aaRS family. Bacterial and mitochondrial PheRSs share a ferredoxin-fold anticodon binding (FDX-ACB) domain, which represents a canonical double split alpha+beta motif having no insertions. The FDX-ACB domain displays a typical RNA recognition fold (RRM) (see PDOC00030) formed by the four-stranded antiparallel beta sheet, with two helices packed against it [PMID: 7664121, PMID: 9016717, PMID: 10049785, PMID: 12962494, PMID: 18611382].
