Abstract

Growth of Escherichia coli in the presence of glyphosate, an inhibitor of aromatic amino acid biosynthesis, has permitted the production of proton translocating ATPase that is specifically labelled with 5-fluorotryptophan. Five sets of 19F nuclear magnetic resonances are resolved. The use of glyphosate should be of wide applicability in the preparation of proteins labelled in aromatic amino acid residues for NMR studies.
