Protein
Peptide methionine sulfoxide reductase 2
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Methionine-R-sulfoxide reductase which catalyzes the reduction of methionine sulfoxide (MetSO) to methionine in proteins. Plays a protective role against oxidative stress by restoring activity to proteins that have been inactivated by methionine oxidation. Protects iron-sulfur clusters from oxidative inactivation along with MXR1. Involved in the regulation of lifespan.
Similarity
Belongs to the MsrB Met sulfoxide reductase family.
