Abstract:
:Sequence-specific assignments of 1H NMR resonances are obtained for the backbone protons of Escherichia coli acyl carrier protein, acylated with an eight-carbon chain covalently attached to the prosthetic group thiol (octanoyl-ACP). Comparison of 1H-1H sequential connectivities in the NOESY spectra of octanoyl-ACP and the unacylated protein (ACPSH) indicates that secondary structure is largely conserved on acylation. Changes in resonance positions observed for certain groups of residues are interpreted in terms of a model that describes the spatial reorientation of secondary structural elements in the protein resulting from introduction of the acyl chain.
