ID 2.5.1.130 DE 2-carboxy-1,4-naphthoquinone phytyltransferase. AN 1,4-diketo-2-naphthoate phytyltransferase. AN 1,4-dioxo-2-naphthoate phytyltransferase. CA 1,4-dioxo-2-naphthoate + H(+) + phytyl diphosphate = CO2 + CA demethylphylloquinone + diphosphate. CC -!- This enzyme, founds in plant and cyanobacteria, catalyzes a step in CC the synthesis of phylloquinone (vitamin K1), an electron carrier CC associated with photosystem I. CC -!- The enzyme catalyzes the transfer of the phytyl chain synthesized by CC EC 1.3.1.83 to 2-carboxy-1,4-naphthoquinone. DR Q0WUA3, MENA_ARATH ; P73962, MENA_SYNY3 ; //
