Purification of Helicobacter pylori superoxide dismutase and cloning and sequencing of the gene

1 Dec 1993

Abstract excerpt

The superoxide dismutase (SOD) of Helicobacter pylori, a pathogenic bacterium which colonizes the gastric mucosa, evoking a marked inflammatory response, was purified and characterized, and the N-terminal amino acid sequence was determined. The enzyme consists of two identical subunits each with an apparent molecular weight of 24,000. Analysis of the primary structure and inhibition studies revealed that H....
