Tetracycline Action Pathway

Homo sapiens
Tetracycline is a short-acting antibiotic that is semi-synthetically produced from chlortetracycline, a compound derived from Streptomyces aureofaciens. Tetracycline enters bacterial cells by passively diffusing through membrane porin channels. Once inside the cell, tetracycline reversibly binds to the 30S subunit just above the binding site for aminoacyl tRNA. At its primary binding site, interactions with the sugar phosphate backbone of residues in helices 31 and 34 via hydrogen bonds with oxygen atoms and hydroxyl groups on the hydrophilic side of the tetracycline help anchor the drug in position. Salt bridge interactions between the backbone of 16S rRNA and tetracycline are mediated by a magnesium ion in the binding site. Tetracycline prevents incoming aminoacyl tRNA from binding to the A site on the ribosome-RNA complex via steric hindrance. This causes inhibition of protein synthesis and hence bacterial cell growth.

Tetracycline Action Pathway

Homo sapiens
Tetracycline is a broad-use antibiotic that is produced by Streptomyces and used to treat bacterial infections such as rocky mountain spotted fever, typhus fever and tick fevers. it is most effectively administered orally but can also be administered via intramuscular injection. It has a half-life of 6-12 hours and is concentrated by the liver and excreted through the urine and feces. Tetracycline can passively transport itself through the bacterial membrane and goes on to inhibit bacterial growth. It stops bacterial growth by binding to the 30S subunits that inhibit the transfer of amino-acyl tRNA to site A of the ribosome. Thus halting protein synthesis and stopping bacterial growth.

Tetracycline Biosynthesis

Kitasatospora aureofaciens
Tetracyclines are aromatic polyketide antibiotics produced via type II polyketide synthases and possess several antibiotic drug properties that work against the activity of Gram-positive and negative bacterial pathogens and are also used to treat several types of bacterial infections in the body. They are natural polyketides produced by actinomycete bacteria like Kitasatospora aureofaciens and are unique by their tetracyclic ring structure and a richly substituted A ring. This pathway shows biosynthesis of naturally occurring tetracyclines (oxytetracycline, tetracycline and chlortetracycline) via the common intermediate anhydrotetracycline. Four genes: oxyE, oxyL, oxyQ, oxyT encode the enzymes that are involved in the modifications that generate anhydrotetracycline. The final two enzymes in the pathway are monooxygenases that are encoded by the gene oxyS and an F420-dependent dehydrogenase encoded by oxyR. OxyS catalyzes two successive monooxygenation reactions where one variation leads to the formation of tetracycline and the other leads to the formation of oxytetracycline. Tetracycline also leads to the formation of chlortetracycline via the enzyme flavin reductase (NADH).
