Abstract excerpt
The insertion mutant HF231 of Alcaligenes eutrophus H16 failed to grow anaerobically on nitrate and nitrite. When grown under oxygen limitation, mutant HF231 specifically excreted coproporphyrin III, an intermediate of heme biosynthesis. With the help of a Tn5-labeled fragment, we identified and...
