Figure 1From: Betalain production is possible in anthocyanin-producing plant species given the presence of DOPA-dioxygenase and L-DOPASchematic of the proposed biosynthesis pathway of betalains. Abbreviations are; 4,5DOD, DOPA-4,5-dioxygenase; DOPA-OX, DOPA oxidase; S, spontaneous conversion; TY-OHase, tyrosine hydroxylase. The steps for formation of the betacyanin glycosides are not shown.Back to article page
