Oxytetracycline is a tetracycline used for treatment of infections caused by a variety of Gram positive and Gram negative microorganisms including Mycoplasma pneumoniae, Pasteurella pestis, Escherichia coli, Haemophilus influenzae (respiratory infections), and Diplococcus pneumoniae. The extensive structure-activity studies referred to above revealed that with one exception, each of the rings in the linear fused tetracyclic nucleus must be six membered and purely carbocyclic for the molecules to retain antibacterial activity. The A site (acceptor site), binds to the aminoacyl tRNA, which holds the new amino acid to be added to the polypeptide chain. The 20 different synthetases match the 20 different amino acids. Each amino acid is joined to the correct tRNA by aminoacyl-tRNA synthetase. Chen Y, Wang L, He HX, Liu ZF.

Structure and Role of tRNA in Protein Synthesis The transfer RNA is a family of about 60 small sized ribonucleic acids that can recognize the codon of mRNA and exhibit a higher affinity for 21 activated amino acids which combines with them and carries them to the site of protein synthesis. Alternatively, point mutations in tRNA genes may induce a conformational change of the tRNA resulting in a decreased stability of the molecule. Oxytetracycline is a tetracycline used for treatment of infections caused by a variety of Gram positive and Gram negative microorganisms including Mycoplasma pneumoniae, Pasteurella pestis, Escherichia coli, Haemophilus influenzae (respiratory infections), and Diplococcus pneumoniae. In modern living cells, that reaction is catalyzed by enzymes called aminoacyl-tRNA synthetases. There is one aminoacyl tRNA synthetase for each of the 20 amino acids and the enzyme can recognize all the anticodons that represent that particular amino acid. Chen Y, Wang L, He HX, Liu ZF. Aminoacyl-tRNA synthetases play a key role in protein biosynthesis by catalyzing the specific aminoacylation of tRNA at their 3' ends, a two step reaction termed "charging" of tRNA. The synthetase catalyzes a covalent bond between them, forming aminoacyl-tRNA or activated amino acid. The arrow indicates the ester linkage between the amino acid and tRNA.
