The present invention relates to novel mutant thioesterase enzymes and naturally-occurring equivalents thereof, compositions made from such enzymes and uses of thioesterase enzymes. In particular, the present invention provides mutant thioesterase enzymes that have altered properties, for example, altered substrate specificity, altered activity, altered selectivity, and/or altered proportional yields in the product mixtures. The present invention also provides polynucleotides encoding such mutant thioesterase enzymes, and vectors and host cells comprising such polynucleotides. The invention further provides for novel uses of thioesterases in the production of various fatty acid derivatives, which are useful as, or as components of, industrial chemicals and fuels.
An engineered thioesterase enzyme which converts a C10, C12, or C14 acyl-ACP substrate to a fatty acid derivative with a greater activity as compared to a wild-type thioesterase enzyme, wherein the engineered thioesterase enzyme comprises an amino acid sequence that is at least 90% identical to SEQ ID NO:
An engineered thioesterase enzyme which converts an acyl-ACP substrate to a fatty acid derivative with a greater yield or an increased percentage of short-chain fatty acid derivatives as compared to a wild-type thioesterase enzyme, wherein the engineered thioesterase enzyme comprises an amino acid sequence that is at least 90% identical to SEQ ID NO:
