DE   aurachin B dehydrogenase.
CA   aurachin B + H2O + NAD(+) = 4-hydroxy-2-methyl-3-oxo-[(2E,6E)-farnesyl]-
CA   3,4-dihydroquinoline 1-oxide + NADH.
CC   -!- The enzyme from the bacterium Stigmatella aurantiaca catalyzes the
CC       final step in the conversion of aurachin C to aurachin B.
CC   -!- In vivo the enzyme catalyzes the reduction of 4-hydroxy-2-methyl-3-
CC       oxo-4-[(2E,6E)-farnesyl]-3,4-dihydroquinoline-1-oxide to form
CC       2-methyl-1-oxo-4-[(2E,6E)-farnesyl]-3,4-dihydroquinoline-3,4-diol
CC       (note that the reactions written above proceed from right to left),
CC       which then undergoes a spontaneous dehydration to form aurachin B.
