  • Title: Analytical strategy for determination of active site sequences in aminoacyl-tRNA synthetases.
    Author: Beauvallet C, Hountondji C, Schmitter JM.
    Journal: J Chromatogr; 1988 Apr 22; 438(2):347-57. PubMed ID: 2838497.
    Abstract:
    Affinity labelling with radioactive, periodate-oxidized tRNA has been used to investigate the structures of tRNA-binding sites in Escherichia coli aminoacyl-tRNA synthetases. Labelled peptides were isolated by means of a combination of techniques involving chymotryptic digestion of the enzyme, gel filtration, ribonuclease digestion of tRNA, chromatography on a TSK 2000 column and reversed-phase chromatography. An isocratic phenylthiohydantoin identification system has been interfaced to a sequencer, allowing the characterization of modified lysine residues by means of both chromatographic retention and liquid scintillation counting.
