About Selenocysteine
Selenocysteine is the 21st proteinogenic amino acid. Selenocysteine exists naturally in all three domains of life, but not in every lineage, as a building block of selenoproteins. Selenocysteine is a cysteine analogue with a selenium-containing selenol group in place of the sulfur-containing thiol group.
