Crystal structure of fosfomycin resistance kinase FomA from Streptomyces wedmorensis.
The fosfomycin resistance protein FomA inactivates fosfomycin by phosphorylation of the phosphonate group of the antibiotic in the presence of ATP and Mg(II). We report the crystal structure of FomA from the fosfomycin biosynthetic gene cluster of Streptomyces wedmorensis in complex with diphosphate and in ternary complex with the nonhydrolyzable ATP analog adenosine 5'-(beta,gamma-imido)-triph...
متن کاملPharmacodynamics of fosfomycin: insights into clinical use for antimicrobial resistance.
The aim of this study was to improve the understanding of the pharmacokinetic-pharmacodynamic relationships of fosfomycin against extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli strains that have different fosfomycin MICs. Our methods included the use of a hollow fiber infection model with three clinical ESBL-producing E. coli strains. Human fosfomycin pharmacokinetic profile...
متن کاملFosfomycin monophosphate and fosfomycin diphosphate, two inactivated fosfomycin derivatives formed by gene products of fomA and fomB from a fosfomycin producing organism Streptomyces wedmorensis.
Fig. 1. Structures of FMand FMderivatives inactivated by gene products offomA andfomB. analysis revealed the presence of six open reading frames with unknownfunctions in the sequenced fragment, in addition to the four genes necessary to FMbiosynthesis. So far studied, most antibiotic-producing Streptomyces possessed resistance genes and regulatory genes in their antibiotic production gene clust...
متن کاملFosfomycin resistance plasmids do not affect fosfomycin transport into Escherichia coli.
Escherichia coli cells carrying fosfomycin resistance plasmids were able to take up fosfomycin from the medium to the same extent as plasmid-free bacteria. The antibiotic entered the plasmid-harboring cells by means of the glpT and uhp transport systems, as is the case with susceptible bacteria. Active fosfomycin could be detected in soluble extracts of cells which had previously been incubated...
متن کاملTransposon Encoding Fosfomycin Resistance
The determinant of resistance to fosfomycin of the Serratia marcescens plasmid pOU900 was transposed into the plasmid ColEl and into the plasmid RP4 in the absence of the RecA function of the host. In each case, the acquisition of fosfomycin resistance was correlated with the presence of a discrete piece of DNA, uniform in size and in restriction pattern. This new, 7.5-megadalton transposable e...
