Identification of respiratory chain gene mutations that shorten replicative life span in yeast
Aging is the progressive accumulation of alterations in cells that elevates the risk of death. The mitochondrial theory of aging postulates that free radicals produced by the mitochondrial respiratory system contribute to ...
Compartmentalization and regulation of mitochondrial function by methionine sulfoxide reductases in yeast
(American Chemical Society, 2010-10)
Elevated levels of reactive oxygen species can damage proteins. Sulfur-containing amino acid residues, cysteine and methionine, are particularly susceptible to such damage. Various enzymes evolved to protect proteins or ...
