Functional characterization of desaturase activity of candidate genes in yeast. Total ion chromatograms of fatty acid methyl ester (FAME) products of Cu2+-induced ole1 elo1 S. cerevisiae yeast supplemented with saturated acyl precursors and transformed with a empty expression vector (control), b pYEX-CHT-Cpo_CPRQ, and c pYEX-CHT-Cpo_SPTQ(1). Confirmation of the identity of enzyme products was obtained by comparison of retention time and mass spectra of synthetic standards. Confirmation of double-bond positions by mass spectra of DMDS adducts (d, e)
