Reductive elimination of superoxide: Structure and mechanism of superoxide reductases
Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2010Superoxide anion is among the deleterious reactive oxygen species, towards which all organisms have specialized detoxifying enzymes. For quite a long time, superoxide elimination was thought to occur through its dismutation, catalyzed by Fe, Cu, and Mn or, as more recently discovered, by Ni-containing enzymes.

Reactions of Superoxide with Myeloperoxidase
Biochemistry, 2007When neutrophils ingest bacteria, they discharge superoxide and myeloperoxidase into phagosomes. Both are essential for killing of the phagocytosed micro-organisms. It is generally accepted that superoxide is a precursor of hydrogen peroxide which myeloperoxidase uses to oxidize chloride to hypochlorous acid. Previously, we demonstrated that superoxide

Superoxide in the Vascular System
Journal of Vascular Research, 2002Oxidant production and regulation is becoming increasingly important in the study of vascular signaling mechanisms, and recent reviews have characterized some of the possible roles for known downstream products of superoxide formation. In this review, we will examine current research in the field, with a special emphasis on the role of the superoxide ...

Development of a superoxide sensor by immobilization of superoxide dismutase
Sensors and Actuators B: Chemical, 2002Abstract Superoxide (O 2 − , one of the reactive oxygen species (ROS)) produced in vivo plays various pathphysiological and physiological roles, and thus it is of great importance and value to evaluate quantitatively dynamic changes in superoxide concentration. We thus aimed at developing a superoxide dismutase (SOD)-immobilized sensor.

Superoxide Dismutases: Defence Against Endogenous Superoxide Radical
2008Attempts to measure the rate of O2- production, in whole cells or in intact subcellular organelles, are frustrated by the endogenous superoxide dismutase (SOD). Streptococcus faecalis contains a single manganese-SOD which was isolated and used as an antigen in the rabbit. A precipitating and inhibiting antibody was obtained and used to suppress the SOD
