Moenomycin: an inhibitor of c55-isoprenoid-alcohol kinase from Staphylococcus aureus

Biochim Biophys Acta. 1976 Oct 22;444(3):783-8.


The effect of a variety of structurally diverse antibiotics on C55-isoprenoid-alcohol kinase (EC from Staphylococcus aureus has been examined. Only moenomycin was found to be inhibitory (Ki = 0.2 mM). Moenocinol, the C25 lipid component of moenomycin, did not serve as a substrate of the kinase reaction and was less inhibitory than the intact antibiotic. It is concluded that the observed inhibition may be due to the structural similarity between C55-isoprenylmonophosphate and the substituted moenocinol moiety of moenomycin.
