Application
Phosphomycin, also known as Fosfomycin, is an antibiotic produced by Streptomyces fradiae. It is used to treat uncomplicated urinary tract infections and to reduce nephrotoxicity and ototoxicity of platinum-containing anti-tumor agents. It is used to study resistance proteins in Bacillus subtilis and Mycobacterium tuberculosis. It is a potential treatment for bronchiectasis.
Biochem/physiol Actions
Fosfomycin is a phosphoenolpyruvate analog. It irreversibly inhibits enolpyruvate transferase (MurA). Therefore, the producion of N-acetylmuramic acid, an essential element of the peptidoglycan cell wall is inhibited.
Phosphomycin calcium salt blocks the formation or N-acetylmuramic acid by inhibiting UDP-Nacetylglucosamine 3-enolpyruvate transferase (MurA).
Other Notes
Keep container tightly closed in a dry and well-ventilated place.

We demonstrate that the Bacillus subtilis fosB(yndN) gene encodes a fosfomycin resistance protein. Expression of fosB requires sigma(W), and both fosB and sigW mutants are fosfomycin sensitive. FosB is a metallothiol transferase related to the FosA class of Mn(2+)-dependent glutathione

Mycobacterium tuberculosis has innate resistance to a range of broad-spectrum antimicrobial agents. This may in part reflect the relative impermeability of the mycobacterial cell wall, but additional specific mechanisms may also be important. In the case of fosfomycin, it has
