FabF1 expression leads a modest conversion of cis-3-decenoyl-[acyl-carrier-protein] to trans-2-cis-5-dodecadienoyl-[acyl carrier-protein]. An Escherichia coli fabF- strain in which Clostridium acetobutylicium FabF1 is expressed from the lac promoter of a low copy number vector closely mimicks the changes in fatty acid composition seen in wild type Escherichia coli strains upon changes in growth temperature. Expression of Clostridium acetobutylicium FabF1 restores cis-vaccenate synthesis at all temperatures, but is much more effective at 30°C than at 37°C or 42°C 702905 2.3.1.179 additional information in vitro complementation of the enzyme-deficient Escherichia coli CY244 strain, shows that Plasmodium falciparum FabB/F functions like Escherichia coli FabF as the growth of the mutant cells can be rescued only in the presence of oleic acid 704117 2.3.1.179 additional information transient silencing of the KASII genes in Nicotiana benthamiana for metabolic engineering of wax ester composition, simultaneous inhibition of the two KASII genes Nicotiana benthamiana is possible using three different RNAi constructs 737248 2.3.1.179 R206G R206 impairs the binding of CoA 718888
