Dopaxanthin
Dopaxanthin is produce from the reaction between dopaxanthin quinone and water, with oxygen as the byproduct. The reaction is catalyzed by the tyrosinase precursor enzyme. Dopaxanthin can also be produced by the reaction between portulacaxanthin II, L-ascorbate, and O2, with L-dehydro-ascorbate and H2O as byproducts. The reaction is also catalyzed by the tyrosinase precursor enzyme. Dopaxanthin is produce from the reaction between dopaxanthin quinone and water, with oxygen as the byproduct. The reaction is catalyzed by the tyrosinase precursor enzyme.
Portulacaxanthin II
Portulacaxanthin II is involved in betaxanthin biosynthesis (via dopaxanthin) pathway. This pathway demonstrates the formation of betaxanthins such as portulacaxanthin II and dopaxanthin by means of non-enzymatic condensation from the amino acids L-tyrosine and L-DOPA, respectively. Tyrosinases have been described as capable to use those betaxanthins [ GandiaHerr05a ] as substrates for further metabolization. [HMDB]. Portulacaxanthin II is found in many foods, some of which are pineappple sage, peppermint, japanese pumpkin, and medlar.
