In the United Kingdom, birds sold as capons are chemically or physically castrated cocks. The origins of caponised chickens are contested. They were known
L-methionine (S)-S-oxide reductase 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 (S)-S-oxide reductase.
