Cloned(Commentary)

Cloned (Comment) Organism
overexpression of msrA gene in HLE cells protects against oxidative stress, while silencing of the gene by short interfering RNA-targeted gene silencing method renders the lens epithelial cells more sensitive to oxidative stress damage Homo sapiens

Natural Substrates Organism Comment (Nat. Sub.) Natural Products Comment (Nat. Pro.) Rev. Reac.
L-methionine (S)-sulfoxide + thioredoxin Homo sapiens oxidation of protein-bound methionine results in loss of protein function, but can be reversed by the enzyme activity reducing methionine sulfoxide L-methionine + thioredoxin disulfide + H2O

additional information Homo sapiens the enzyme is an essential regulator of longevity and is important for lens cell viability and resistance to oxidative stress, methionine sulfoxide is the major oxidative stress product, up to 60%, in cataract while being essentially absent in clear lens ?
