Purification and NMR characterization of acyl carrier protein

The acyl carrier protein preparation obtained using the 2-propanol method of Rock and Cronan (Rock, C. O., and Cronan, J. E., Jr. (1981) Methods Enzymol. 71, 341-351) can be further purified with reversed-phase high-performance liquid chromatography. A homogeneous sample of acyl carrier protein is obtained as determined by NMR and reversed-phase high-performance liquid chromatography.
