Gene construct encoding mutant thioesterase, mutant thioesterase encoded thereby, transformed host cell containing the gene construct, and method of using them to produce medium-chain fatty acids

摘要

Unnatural, mutated thioesterases having an amino acid sequence that is at least 80% identical to SEQ. ID. NO: 1 and having substitutions at one or more of amino acid positions I107, R108, L109, S122, M141, E142, Y145, and L146, gene constructs encoding and configured to express the mutated thioesterases in a transformed host cell and host cells transformed to contain the gene constructs.
