The structures of lauroyl–AMP and lauroyl–CoA are incorrectly represented in Fig. 1c, d of this Letter, which shows the L-form rather than the natural D-form of adenosine; there is no phosphate group at the 2′-position of the ribosyl moiety of lauroyl–AMP (Fig. 1c) and the phosphate group in lauroyl–CoA (Fig. 1d) should be at the 3′-position. These errors do not affect our conclusions.
