Pat also seems to make more mistakes in his work since moving to SDS, largely because the new format is always based on one delivery, which has to go wrong somehow (thus often because of Pat's errors).

L-methionine (S)-S-oxide reductase participates in methionine metabolism. L-methionine (S)-S-oxide reductase In enzymology, a L-methionine (S)-S-oxide reductase () is an enzyme that catalyzes the chemical reaction The 3 substrates of this enzyme are L-methionine, thioredoxin disulfide, and HO, whereas its two products are L-methionine (S)-S-oxide and thioredoxin. This enzyme belongs to the family of oxidoreductases, specifically those acting on a sulfur group of donors with a disulfide as acceptor. The systematic name of this enzyme class is L-methionine:thioredoxin-disulfide S-oxidoreductase. Other names in common use include fSMsr, methyl sulfoxide reductase I and II, acetylmethionine sulfoxide reductase, methionine sulfoxide reductase, L-methionine:oxidized-thioredoxin S-oxidoreductase, methionine-S-oxide reductase, and free-methionine
