Microbial Transformation of Antibiotics: Phosphorylation
نویسندگان
چکیده
Addition of clindamycin to whole-cell cultures of Streptomyces coelicolor MUller resulted in the loss of in vitro activity against organisms sensitive to clindamycin. Incubation of such culture filtrates with alkaline phosphatase generated a biologically active material identified as clindamycin. Fermentation broths containing inactivated clindamycin yielded clindamycin 3-phosphate, the structure of which was established by physical-chemical and enzymatic studies. Clindamycin was phosphorylated by lysates and partially purified enzyme preparations from S. coelicolor MUller. These reactions require a ribonucleoside triphosphate and Mg2+. The product of the cell-free reactions was identified as clindamycin 3-phosphate.

Microbial transformations of antibiotics.
In spite of their unusual molecular structures and seemingly high degree of biological recalcitrance, many antibiotics have been shown to be susceptible to microbial attack. Among the types of changes brought about by microbial systems are: (i) acylation; (ii) phosphorylation; (iii) adenylylation and ribonucleotide formation; (iv) hydrolysis; (v) oxidation; (vi) suiph oxidation; (vii) reduction...

Crude enzymepreparations of Streptomyces coelicolor (Miiller), UC 5240 in the presence of ATP and Mg2+ catalyzed the conversion of oleandomycin, tylosin, leucomycin A3 and a mixture of spiramycins I, II and III to their antibiotically inactive I'-O-phosphates.10 Under identical conditions, erythromycin was converted to anhydroerythromycin-Z'-O-phosphate.10 As O-phosphorylation of aminocyclitols...
متن کاملMicrobial transformation of antibiotics. VI. Acylation of chloramphenicol by Streptomyces coelicolor.
Previous papers in this series have described the microbial transformation of clindamycin to clindamycm-S-phosphate1^ Ndemethylclindamycin2), clindamycin sulfoxide2) or clindamycin ribonucleotides3) by Streptomyces species. We have extended our observations on the ability of these organisms to transform antibiotics, to chloramphenicol (I, Fig. 1) which, like clindamycin, binds at the 50S riboso...

Mycobacterium smegmatis PTCC 1307 (CIP 73.26) was used as a microbial agent to produce androsta-1,4-diene-3,17-dione (ADD) and androst-4-ene-3,17-dione, two useful precursors in the synthesis of steroid drugs. The side chain of cholesterol, as the substrate, was selectively cleaved in the presence of five enzyme inhibitors. An intermediate structure with intact side chain, cholest-4-ene-3-one, ...

Background: Pelvic inflammatory disease is a clinical syndrome that has wide range of infections and inflammatory diseases of the upper female genital tract. Microbiological researches revealed that multiple bacteria have been identified as causative agents and several types of antibiotics are required to cover causative pathogens. The choice of an appropriate treatment mostly depended on antim...
