A manganese-containing superoxide dismutase (EC 1.15.1.1) was purified to homogeneity from a higher plant for the first time. The enzyme was isolated from Pisum sativum leaf extracts by thermal ...

The enzyme manganese superoxide dismutase (MnSOD) plays a critical role in maintaining human health by keeping the amount of harmful reactive oxygen molecules in cells under control. By using neutron ...

It has been known in biology for a long time that the excited oxygen molecule singlet oxygen is the main cause of aging in cells. To counter this, nature uses an enzyme called superoxide dismutase to ...

Oxidative stress is caused by an imbalance between production and accumulation of oxygen reactive species (ROS) in cells and tissues. Manganese superoxide dismutase (MnSOD) is an antioxidant enzyme ...

Responses of superoxide dismutase (EC 1.15.1.1) and glutathione reductase (EC 1.6.4.2) activities were evaluated in leaf tissue from intact cotton plants (Cotton Branch 1697) which were exposed to 75% ...

Superoxide dismutase (SOD) genes encode a family of critical metalloenzymes that serve as a first line of defence against oxidative damage in plants. By converting the superoxide radical into less ...

Ten years ago, researchers linked familial amyotrophic lateral sclerosis (FALS) to mutations in SOD1 (superoxide dismutase 1), which encodes a copper-containing superoxide dismutase enzyme known as ...

Enzymes, the core catalysts in life, drive critical biological processes ranging from metabolic regulation to energy conversion. Evolved over billions of years, these versatile molecular machines not ...

DURHAM, N.C. -- An enzyme that protects the body from reactive chemicals called free radicals is crucial in preventing the inflammation that causes chronic lung disease in premature infants, according ...

Mitochondria, known as the powerhouses within human cells, generate the energy needed for cell survival. However, as a byproduct of this process, mitochondria also produce reactive oxygen species (ROS ...
