CRYSTAL STRUCTURE OF THE 4'-PHOSPHOPANTETHEINYL TRANSFERASE SFP-COENZYME A COMPLEX


Overview

The Bacillus subtilis Sfp protein activates the peptidyl carrier protein (PCP) domains of surfactin synthetase by transferring the 4'-phosphopantetheinyl moiety of coenzyme A (CoA) to a serine residue conserved in all PCPs. Its wide PCP substrate spectrum renders Sfp a biotechnologically valuable enzyme for use in combinatorial non-ribosomal peptide synthesis. The structure of the Sfp-CoA complex determined at 1.8 A resolution reveals a novel alpha/beta-fold exhibiting an unexpected intramolecular 2-fold pseudosymmetry. This suggests a similar fold and dimerization mode for the homodimeric phosphopantetheinyl transferases such as acyl carrier protein synthase. The active site of Sfp accommodates a magnesium ion, which is complexed by the CoA pyrophosphate, the side chains of three acidic amino acids and one water molecule. CoA is bound in a fashion that differs in many aspects from all known CoA-protein complex structures. The structure reveals regions likely to be involved in the interaction with the PCP substrate.
