ID 1.3.1.78 DE arogenate dehydrogenase (NADP(+)). AN arogenic dehydrogenase. AN pretyrosine dehydrogenase. AN TyrAa. AN TyrAAT1. AN TyrAAT2. CA L-arogenate + NADP(+) = CO2 + L-tyrosine + NADPH. CC -!- Arogenate dehydrogenases may utilize NAD(+) (EC 1.3.1.43), NADP(+) CC (EC 1.3.1.78), or both (EC 1.3.1.79). CC -!- NADP(+)-dependent enzymes usually predominate in higher plants. CC -!- The enzyme from the cyanobacterium Synechocystis sp. PCC 6803 and the CC TyrAAT1 isoform of the plant Arabidopsis thaliana cannot use CC prephenate as a substrate, while the Arabidopsis isoform TyrAAT2 can CC use it very poorly.
