CrCPR-CsF3H-GhF3'H-AaDFR-DuLAR level2

It is a composite part of catechin metabolic pathway. pGAL1-CrCPR-tTDH1-pTEF1-CsF3H-tENO2-pPGK1-GHF3'H-tADH1-pTDH3-AaDFR-tENO1-pPOP6-DuLAR-tSSA1

Assembly of synthesis pathway of catechin, shown by Fig.1.

Fermentation results by HPLC test

During the HPLC testing, we purchased final and intermediate metabolism products standard, naringenin, taxifolin, eriodictyol and catechin, and used them in the subsequent HPLC tests.

Figure 2: [2] Fig.2 The results of HPLC of naringenin, taxifolin, eriodictyol, catechin standard and sample from fermentation medium

As shown in Fig.2, since we could not buy leucoanthocyanidins (LCD), we only did HPLC of the four intermediates: Catechin, Eriodictyol, Taxifolin and Naringenin. Catechin and other intermediate metabolites were confirmed by comparing the samples with the standard.
