ID 2.5.1.74 DE 1,4-dihydroxy-2-naphthoate polyprenyltransferase. CA 1,4-dihydroxy-2-naphthoate + an all-trans-polyprenyl diphosphate + H(+) = CA a 2-demethylmenaquinol + CO2 + diphosphate. CC -!- This enzyme catalyzes a step in the synthesis of menaquinone, CC in which the prenyl chain synthesized by polyprenyl diphosphate CC synthase is transferred to 1,4-dihydroxy-2-naphthoate (DHNA). CC -!- The bacterial enzyme is an inner membrane protein, with the CC C-terminus located in the periplasm. CC -!- It is highly specific for DHNA but not for a specific length of the CC prenyl chain.
