/L 548411 /O 195 xref Abstract. Tetracycline is an antibiotic that fights infection caused by bacteria.. Tetracycline is used to treat many different bacterial infections of the skin, intestines, respiratory tract, urinary tract, genitals, lymph nodes, and other body systems. <> J. J.

These reactions are typically performed by dedicated cyclases (Hertweck, 2007).Surprisingly, only two cyclases, OxyK and OxyN, are required to cyclize all four rings during tetracycline biosynthesis, as shown by Zhang et al. 0000022909 00000 n Research on the biosynthesis of tetracyclines, which has developed rapidly since the discovery of chlortetracycline (Duggar 1948), oxytetracycline (Finlay et al. Environmental factors, such as carbon, nitrogen, inorganic phosphate, metal ion and other nutrient sources, cultivation condition parameters, such as pH and aeration (dO 2), and cultivation methods in general, may affect the timing and the extent of TC production (43, 75, 76). >> /T 544526 >> >> Tetracyclines have been important agents in combating infectious disease since their discovery in the mid-20th century.
