Manganese supplementation relieves the phenotypic deficits seen in superoxide-dismutase-null Escherichia coli.

Archives of biochemistry and biophysics - 1 Jun 2002

Al-Maghrebi May, Fridovich Irwin, Benov Ludmil

Abstract excerpt

Escherichia coli, lacking cytoplasmic superoxide dismutases, exhibits a variety of oxygen-dependent phenotypic deficits. Enrichment of the growth medium with Mn(II) relieved those deficits. Extracts of cells grown on Mn(II)-rich medium exhibited superoxide dismutase-like activity that was due partially to low-molecular-weight and partially to high-molecular-weight complexes. The high-molecular-weight activity was...
