Identification
HMDB Protein ID CDBP04333
Secondary Accession Numbers Not Available
Name Methionine-R-sulfoxide reductase B2, mitochondrial
Description Not Available
Synonyms
  1. MsrB2
Gene Name MSRB2
Protein Type Enzyme
Biological Properties
General Function Involved in peptide-methionine-(S)-S-oxide reductase activity
Specific Function Catalyzes the reduction of free and protein-bound methionine sulfoxide to methionine (By similarity). Upon oxidative stress, may play a role in the preservation of mitochondrial integrity by decreasing the intracellular reactive oxygen species build-up through its scavenging role, hence contributing to cell survival and protein maintenance.
