Fig. 8 in Comparison of glucosinolate diversity in the crucifer tribe Cardamineae and the remaining order Brassicales highlights repetitive evolutionary loss and gain of biosynthetic steps

Fig. 8. Biochemical aspects of aliphatic side chain oxidation of glucosinolates (GSLs). A. Biosynthesis of three well-investigated GSLs, all involving enzymes of the class "2-oxoglutarate-dependent dioxygenases", although the case of BAR biosynthesis is still tentative (Byrne et al., 2017). B. Conserved metabolism of an OAT into the corresponding oxazolidine-2-one (OAO) in three Brassicales species (Barbarea vulgaris, Nasturtium officinale and Reseda luteola). MYR, myrosinase; GS-OH, glucosinolate hydroxylating enzyme; GRS, glucoraphasatin synthase.
