Fig. 2From: Combination of ester biosynthesis and ω-oxidation for production of mono-ethyl dicarboxylic acids and di-ethyl esters in a whole-cell biocatalytic setup with Escherichia coli Mass spectra of products in assays with AlkK. a mass spectrum of the formed product in incubations with cell free extract of E. coli pET-Duet-alkK and octanoic acid. The m/z of 892 corresponds to octanoyl-CoA. b mass spectrum of the formed product in incubations with cell free extract of E. coli pET-Duet-alkK and mono-ethyl suberate. The m/z of 950 corresponds to the CoA-ester of mono-ethyl suberate. The M−+22*n peaks indicate sodium adductsBack to article page
