Abstract

Genes encoding mutant 3-ketoacyl-CoA synthases are introduced into host cells. Certain of the mutants enhance the production of shorter-chain fatty acids and derivatives by the cell than do the wild-type (unmutated) enzymes. In other cases, the chain length is not significantly affected, but productivity is enhanced. In specific cases, both a shift toward lower chain length and higher productivity is seen. Cells producing the mutant 3-ketoacyl-CoA synthases are especially suitable for producing C6-C10 fatty acids and derivatives.
