We have used 13C nuclear magnetic resonance to monitor acetate metabolism in a proline-overproducing strain of Escherichia coli growing on 13C-labeled acetate. The conversion of 13C-labeled acetate to proline by actively dividing cells was followed in vivo, and the site specificity of the incorporation of the acetate carbons in the proline was determined from spectra of butanol extracts of the growth media. The degree of incorporation of deuterium from partially deuterated water into various sites on the proline was monitored from the beta-deuterium-shifted signals in the 13C spectra. The spectra provide information on the origin of the carbons and the protons during proline biosynthesis.
