MATERIALS AND METHODS FOR PRODUCTION OF BI-FUNCTIONAL FATTY ACIDS IN RECOMBINANT BACTERIA

摘要

A method of producing bi-functional fatty acids comprising introducing into a host cell or organism, which comprises one or more ω- or ω-1 functionalized acyl-CoAs, and expressing therein a KASIII, which can use one or more of the ω- or ω-1 functionalized acyl-CoAs as a substrate; a method of producing a ω-1 hydroxy branched fatty acid, a ω-1 branched fatty acid, or a combination thereof by culturing a mutant E. coli, which does not express a functional KASIII from the endogenous fabH gene and expresses a phaA and a phaB and a functional exogenous KASIII; and a mutant E. coli, a method of making the mutant, a culture comprising the mutant, and a composition comprising ω-1 hydroxy branched fatty acids, a ω-1 branched fatty acids, or a combination thereof obtained from the culture.

1. A method of producing bi-functional fatty acids in a host cell or organism, which method comprises introducing into a host cell or organism, which comprises one or more ω- or ω-1 functionalized acyl-CoAs, and expressing therein a nucleic acid molecule comprising a nucleotide sequence encoding a 3-ketoacyl-acyl carrier protein (ACP) synthase III (KASIII), which can use one or more of the ω- or ω-1 functionalized acyl-CoAs as a substrate, whereupon bi-functional fatty acids in the host cell or organism are produced.
