Purification and characterization of the periplasmic nitrate reductase from Thiosphaera pantotropha.

European journal of biochemistry - 15 Feb 1994

Berks B C, Richardson D J, Robinson C, Reilly A, Aplin R T, Ferguson S J

Abstract excerpt

The periplasmic nitrate reductase of Thiosphaera pantotropha has been purified from a mutant strain (M-6) that overproduces the enzyme activity under anaerobic growth conditions. The enzyme is a complex of a 93-kDa polypeptide and a 16-kDa nitrate-oxidizable cytochrome c552. The complex contains molybdenum; a fluorescent compound with spectral features of a pterin derivative can be extracted. In contrast to the...
