Metabolite Identification
Common NameMethionine sulfoxide
DescriptionMethionine sulfoxide (MetO) or L-Methionine sulfoxide belongs to the class of organic compounds known as L-alpha-amino acids. These are alpha amino acids which have the L-configuration of the alpha-carbon atom. Methionine sulfoxide arises through the oxidation of methionine residues in proteins by reactive oxygen species (ROS). Oxidation of methionine results in a mixture of the two diastereomers methionine-S-sulfoxide and methionine-R-sulfoxide. Methionine oxidation is considered an important post-translational event in protein synthesis and can affect the function and activity of many proteins. The oxidation of methionine plays an important role in vivo, during biological conditions of oxidative stress, as well as for protein stability in vitro. For instance, the oxidation of methionine residues in tissue proteins can cause them to misfold or otherwise render them dysfunctional. Most organisms have developed systems to restore these oxidized methionine residues back to methionine (i.e., converting MetO to Met). This reduction is done by the methionine sulfoxide reductase (MSR) system, with the MSRs type A (MSRA) and type B (MSRB) being specific for the S and R forms of MetO, respectively (PMID: 28917052 ). In mammals, the selenoprotein MSRB1 plays an important MetO repair function, and its expression is tightly regulated by dietary selenium (PMID: 28917052 ). The eventual proteolyis of any unfolded or misfolded MetO modified proteins leads to the production of free methionine sulfoxide that can be detected in blood or urine.  MetO is not a proteogenic amino acid and cannot be incorporated into proteins during ribosomal mediated translation. Levels of free MetO are closely correlated with levels of oxidative stress. Methionine sulfoxide (MetO), increases with age in body tissues, and its presence is believed by some to contribute to biological aging.  Levels of MetO are also increased in individuals suffering from chronic bacterial infections (tuberculosis) or other conditions causing inflammation (PMID: 32123207 ). Similarly, MetO is increased in the serum/plasma of patients diagnosed with sepsis (PMID: 27501420 ). This likely reflects the high production of ROS species arising from the overactive (but underperforming) immune response.

Enzymes

General function:
Involved in oxidoreductase activity, acting on a sulfur group of donors, disulfide as acceptor
Specific function:
Has an important function as a repair enzyme for proteins that have been inactivated by oxidation. Catalyzes the reversible oxidation-reduction of methionine sulfoxide in proteins to methionine.
Gene Name:
MSRA
Uniprot ID:
Q9UJ68
Molecular weight:
21737.41
Reactions
L-Methionine + thioredoxin disulfide + Water → Methionine sulfoxide + thioredoxindetails
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.
Gene Name:
MSRB2
Uniprot ID:
Q9Y3D2
Molecular weight:
19536.055
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. Isoform 2 is essential for hearing.
Gene Name:
MSRB3
Uniprot ID:
Q8IXL7
