    In the translation of the genetic code each aminoacyl-tRNA synthetase (aaRS) must recognize its own (cognate) tRNA and attach the corresponding amino acid to the acceptor end of tRNA, discriminating all the others. The(alphabeta)2 phenylalanyl-tRNA synthetase (PheRS) is one of the most complex enzymes in the aaRS family and is characterized by anomalous charging properties. Structurally, the enzyme belongs to class II aaRSs, as its catalytic domain is built around an antiparallel beta sheet, but functionally it resembles class I as it aminoacylates the 2'OH of the terminal ribose of tRNA (class II aaRSs aminoacylate the 3'OH). With the availability of the three-dimensional structure of the complex between multisubunit PheRS and tRNAPhe, a fuller picture of the specific tRNA-aaRS interactions is beginning to emerge.
