Glutamyl Adenylate Analogues Are Inhibitors of Glutamyl-tRNA Synthetase
摘要:
Glutamol adenylate 10 was a competitive inhibitor (K-i = 3 pM) of glutamyl-tRNA synthetase from Escherichia coli. The N-6-benzoyl adenine derivative 9 was also an inhibitor (K-i similar to 60 mu M). Replacement of adenine by other bases (purine, cytosine, dihydrocytosine, uridine) resulted in a more than 1000-fold loss in activity, indicating the important contribution of the adenine ring to the enzyme binding.
