Summary

Twenty nine nitrate reductase-less mutants ofEscherichia coli K12 were isolated and characterised asnar(chl)A -,B - orE -. Data from phageP1-mediated transduction studies permitted the construction of fine structure maps fornarA andnarE and suggested that both loci may be functionally divisible into two contiguous genes.NarB was shown to comprise at least three complementation groups.
