A Mutant Defective in Electron Transfer to Nitrate in Free

Abstract

A mutant of K12 is described which is unable to reduce nitrate with a variety of physiological electron donors but which retains nitrate reductase activity with the artificial electron donor benzyl viologen. It is suggested that the affected gene, , located close to , encodes the cytochrome apoprotein.
