Abstract
The Superoxide radical (O2−), produced by the univalent reduction of molecular oxygen, is known to cause cellular damage due to its reactive nature. Superoxide dismutases (SODs) are a group of metalloenzymes which protect against the deleterious effects of Superoxide by catalyzing its conversion to hydrogen peroxide and oxygen. Studies are underway to ascertain the role of SOD as a protective enzyme against oxygen toxicity in Trichodesmium. Initial experiments revealed that this organism’s SOD is likely the iron-containing metallotype, as has been found in other cyanobacteria. Preliminary data also indicate that SOD activity varies in Trichodesmium on a diel basis, being the highest in the early morning, decreasing throughout the day, and reaching a low during the night.
