Pathway Edits

ANR differential expression (anthocyanidin reductase) for epicatechin flux control
LAR allelic balancing (leucoanthocyanidin reductase) for catechin:epicatechin ratio
F3-5H overexpression (flavonoid 3',5'-hydroxylase) for gallated catechin precursor enrichment
DFR allelic selection for 3',4'- vs 3',4',5'-dihydroxyl substrate preference
FLS suppression (flavonol synthase) to redirect dihydroflavonol flux toward catechins
Cell-free wheat germ extract reconstitution system
Enhanced flux via 5'UTR synthetic leader sequence optimization
