Streptomyces coelicolor A3(2) synthesizes three membrane-associated respiratory nitrate reductases (Nars). During aerobic growth in liquid medium the bacterium was able to reduce 50 mM nitrate stoichiometrically to nitrite. Construction and analysis of a mutant in which all three narGHJI operons were deleted showed that it failed to reduce nitrate. Deletion of the gene encoding MoaA, which catalyses the...
