Gas Chromatography Mass Spectrum of Alpha-pinene Synthase Products: We expressed the alpha-pinene synthase (BBa_K517002) in C41 DE3 E. coli and lysed the cell culture to obtain protein extract which was run through a nickel column to purify the HIS-tagged alpha-pinene synthase. The purified synthase was used in an in vitro enzymatic assay to produce alpha-pinene from geranyl diphosphate (GPP) substrate. (A) Monoterpene product spectrum of our alpha-pinene synthase. Through gas chromatography mass spectrometry, we analysed the products of the alpha-pinene synthase and found alpha-pinene, beta-pinene and small quantities of other monoterpenes. This product spectrum agrees with prior findings (Keeling et al. 2011 BMC Plant Biology). (B) Identification of alpha-pinene as a product. Cross referencing with standards and a compound library revealed that the alpha-pinene product had the characteristic base peaks and retention time of 3.6 minutes. Top panel displays peak spectrum for our sample. Bottom panel displays peak spectrum for library standard. (C) Identification of beta-pinene as a product. Cross referencing with standards and a compound library revealed that the beta-pinene product had the characteristic base peaks and retention time of 5.6 minutes. Top panel displays peak spectrum for our sample. Bottom panel displays peak spectrum for library standard.
