VLCFAs are synthesized by fatty acid elongase (FAE), which is an integral membrane enzyme system with multiple components. The genetic complexity of the FAE system, and its membrane association has hampered the biochemical characterization of FAE. In this study we computationally identified Zea mays genetic sequences that encode the enzymatic components of FAE and developed a heterologous expression system to evaluate their functionality. The ability of the maize components to genetically complement <i>Saccharomyces cerevisiae</i> lethal mutants confirmed the functionality of ZmKCS4, ZmELO1, ZmKCR1, ZmKCR2, ZmHCD and ZmECR, and the VLCFA profiles of the resulting strains were used to infer the ability of each enzyme component to determine the product profile of FAE. <div><br></div><div>Data included within this entry are the fatty acid accumulation fingerprints which together builds the product profile of each yeast strain. Fatty acids were extracted from lyophilized yeast cell pellets by base-hydrolysis. Extracts were run on a GC-MS and/or GC-FID, and quantification was done using an internal standard (19 carbon fatty acid).
