IDH2 Gene

        Isocitrate dehydrogenase (IDH) is a key enzyme in the TCA cycle, which can provide reducing power for cell growth, and participate in algal energy metabolism and anabolism[1]. IDH2 is the gene encoded in Y.lipolytica. It was registered in 2019. In order to characterize the effect of the IDH2 gene in lipid synthesis and growth, we constructed a knockout strain po1f ΔylIDH2 using homologous recombination. The YNB medium have been chosen for testing Results showed that the strain po1f ΔylIDH2 can effectively increase the accumulation of biomass and fatty acid content. Among them, the strain po1f ΔylIDH2 biomass and fatty acid content increased by 5.63% and 10.10%, respectively. These results provide references for future iGEM teams to improve biomass and lipid accumulation in Y.lipolytica.
