Engineering the Production of Major Catechins by Escherichia coli Carrying Metabolite Genes of Camellia sinensis

Figure 1

The proposed pathways for the biosynthesis of catechins in tea leaves. Enzymes are CHS: chalcone synthase; CHI: chalcone isomerase; F3H: flavanone 3-hydroxylase; DFR: dihydroflavonol reductase; LCR: leucoanthocyanidin reductase. (Adopted from Park et al. [1]).
