the enzyme catalyzes the second step in the biosynthetic pathway from aurachin C to aurachin B. Aurachin C is first converted to 3,4-dihydroxy-2-methy-4-[(2E,6E)-farnesyl]-3,4-dihydroquinoline 1-oxide by enzyme AuaG, which is then reduced to aurachin B. The pathway involves the migration of the prenyl group from position C3 to C4, probably via a pinacol type rearrangement. The equilibrium state of AuaG and the instability of 3,4-dihydroxy-2-methy-4-[(2E,6E)-farnesyl]-3,4-dihydroquinoline 1-oxide suggests the requirement of immediate reduction catalyzed by AuaH to fix the farnesyl group at the position C4 and prevent the degradation of the intermediate |
