3.2.1.168 additional information catalysis of rutin hydrolysis (EC 3.2.1.168) and transglycosylation of phenol acceptors by rutinase. Preparation of rutinosides of phenolic acids (vanillic acid, sinapic acid, ferulic acid, and caffeic acid) using the reverse reaction of hydrolysis by rutinase, derived from tartary buckwheat (Fagopyrum tataricum) seeds. Rutinase is used to transfer the rutinose moiety from rutin (sugar donor) to the phenolic acids. The transglycosylation products are detected by NMR spectroscopy. Rutinosylation proceeds at the primary hydroxyl group of rutinose. In the rutinosylation of vanillic acid, sinapic acid, and ferulic acid, a hydroxyl group at the 4-position of the aromatic ring was rutinosylated. When caffeic acid, which contains two hydroxyl groups in the ortho position, is used as the acceptor, the hydroxyl group at the 3-position of the aromatic ring was conjugated to rutinose. Rutinase has high substrate specificity for rutin (quercetin-3-rutinoside) and does not degrade structural homologues such as naringin (naringenin-7-rhamnoglucoside) and quercitrin (quercetin 3-rhamnoside). Phenolic compounds containing two terminal aromatic groups, such as curcumin, nordihydroguaiaretic acid (NDGA), and resveratrol, do not form rutinosides Fagopyrum tataricum ?
