Fluorine-19 nuclear magnetic resonance study of 5-fluorotryptophan-labeled histidine-binding protein J of Salmonella typhimurium

Fluorine-19 nuclear magnetic resonance has been used to investigate the histidinebinding protein J from Salmonella typhimurium. The protein has been labeled with fluorine-19 by growing the bacterial cells of a tryptophan auxotroph in the presence of 5-fluorotryptophan. Incorporation of up to 70% was...
