Materials and MethodsACP was isolated from E. coli B cells (Grain Processing) by using the method of Rockand Cronan (1980) and reduced with dithiothreitol (DTT) to the free sulfhydryl form. ACP samples were passed through a short Chelex column, followed by a Sephadex G-25 column (5 mM potassium phosphate buffer) and freeze-dried. HPLC and NMR analyses showed these samples to contain approximately 10% minor isostruc-tural forms of ACP. The samples were deemed sufficiently pure for NMR analysis since it was felt that the 10% con-taminants were unlikely to give observable resonances. This has proven to be largely correct. There are, however, a few weak cross-peaks present in the amide-C “H region of the1 Abbreviations: ACP, acyl carrier protein; DTT, dithiothreitol; ß-EA-SH,/3-mercaptoethylamine; 2D NMR, two-dimensional nuclear magnetic resonance; COSY, two-dimensional/-correlated NMR spectroscopy; DQF-COSY, double quantum filtered COSY; RELAYEDCOSY (RELAY), relayed coherence transfer spectroscopy; NOE, nu-clear Overhauser effect; NOESY, two-dimensional NOE spectroscopy; ppm, parts per million; day {ij), cross relaxation connectivity between the C “H proton on residue i and the amide proton on residue j\dgN (iJ), cross relaxation connectivity between a CflH proton on residue i and the amide proton on residue j; d^\¡(t, j), cross relaxation connectivity between the amide proton on residue i and the amide proton on residue j.
