Superoxide Dismutase from Streptococcus mutuns ISOLATION AND CHARACTERIZATION OF TWO FORMS OF THE ENZYME

Abstract

Superoxide dismutase, which catalyzes the dismutation of univalently reduced oxygen (Op-. + 02-. + 2 H+ ---) 0 2 + Hg02) has been shown in mammalian cells to contain copper and zinc. The only reported isolation of the enzyme from a procaryotic organism, Escherichia coli, showed the enzyme to contain only manganese and to differ from the mammalian enzyme in… (More)
