OBJECTIVES Iclaprim is a novel 2,4-diaminopyrimidine that exhibits potent, rapid bactericidal activity against major Gram-positive pathogens, including methicillin-susceptible Staphylococcus aureus and methicillin-resistant S. aureus, and is currently in clinical development for the treatment of complicated skin and skin structure infections. An… (More)
The bacterial phosphoenolpyruvate-sugar phosphotransferase system (PTS) mediates the uptake and phosphorylation of carbohydrates and is involved in signal transduction. In response to the availability of carbohydrates it modulates catabolite repression, intermediate metabolism, gene expression and chemotaxis. It is ubiquitous in bacteria but does not occur… (More)
The phosphoenolpyruvate(P-pyruvate)-dependent sugar phosphotransferase system (PTS) is a transport and signal-transduction system which is almost ubiquitous in bacteria but does not occur in eucaryotes. It catalyzes the uptake and phosphorylation of carbohydrates and is involved in signal transduction, e.g. catabolite repression, chemotaxis, and allosteric… (More)
The phosphoenolpyruvate : sugar phosphotransferase system (PTS) catalyses translocation with concomitant phosphorylation of sugars and hexitols and it regulates metabolism in response to the availability of carbohydrates. The PTS forms an interface between energy and signal transduction and its inhibition is likely to have pleiotropic effects. It is present… (More)
A series of isoxazole-3-hydroxamic acid derivatives has been identified as a new class of small, nonpeptidic inhibitors of peptide deformylase (PDF). The synthesis, enzyme inhibition and preliminary investigation of the binding mode of this potential antibacterial compounds are reported.
The N-acetyl-D-glucosamine transporter (IIGlcNAc) of the bacterial phosphotransferase system couples vectorial translocation to phosphorylation of the transported GlcNAc. IIGlcNAc of Escherichia coli containing a carboxyl-terminal affinity tag of six histidines was purified by Ni2+ chelate affinity chromatography. 4 mg of purified protein was obtained from… (More)
Starting from the NMR structure of the binary complex between the N-terminal domain of the unphosphorylated enzyme I (EIN) of the phosphoenolpyruvate:sugar phosphotransferase (PTS) and the histidine-containing phosphocarrier protein (HPr), a molecular model of the phosphorylated transition state of the related complex was established using constrained… (More)
Thiosemicarbazones react quantitatively with omega-bromoacetophenone in a suitable medium; hydrobromic acid thus formed is titrated alkalimetrically with Thymol Blue as indicator..
