Abstract
A structural model of the enoyl reductase (ER) catalytic domain of the fungal highly-reducing polyketide synthase squalestatin tetraketide synthase (SQTKS) was developed. Simulated docking of substrates and inhibitors allowed the definition of active site residues involved in catalysis and substrate selectivity. These were investigatedin silicowith the aim of extending the substrate scope. Residues were identified which limit the substrate selectivity of the SQTKS ER, and these were mutated and the engineered ER domain assayedin vitro. Significant changes to the programming of the mutant SQTKS ER domains were observed allowing the processing of longer and more methylated substrates.
