Abstract:
The review deals with interactions of the key enzymes of the protein biosynthesis-aminoacyl-tRNA synthetases (EC 6.1.1.) with amino acids and their analogues, considering the contribution of different groups in the process of specific complex formation and catalysis. The important role of alpha-amino group of amino acid in the enzyme recognition has been revealed. Modification of the carboxylic group does not change significantly the analogues complex formation with aminoacyl-tRNA synthetases. However this group is essential for amino acid rearrangement in the specific complex with the enzyme. The structural organization of the enzyme binding sites specific for amino acids and the enzyme interaction with the analogues of aminoacyladenylates are discussed.
