Gene Synthesis The four tandem UAS1B sequence fragment, UAS1B4 was synthesized (Genscript, Nanjing, China), flanked with Cla I-Hin dIII-Spe I sites on the 5′-end and Mlu I-Xba I sites on the 3′-end. The synthetic UAS1B4 sequence was inserted into pUC57 to form pUC-UAS1B4. Get A Quote

摘要

Conjugated linoleic acid (CLA) has been extensively studied for decades because of its health benefits including cancer prevention, anti-atherogenic and anti-obesity effects, and modulation of the immune system. We previously described the production of trans-10, cis-12 CLA in Yarrowia lipolytica by expressing the gene coding for linoleic acid isomerase from Propionibacterium acnes (pai). However the stable strain produced CLA at about 0.08% of dry cell weight (DCW), a level of production which was not high enough for practical applications. The goal of the present study was to enhance production of CLA by genetic engineering of Y. lipolytica strains.
