Common NameSelenocystine
DescriptionSelenocystine belongs to the class of organic compounds known as alpha amino acids. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). In the newer R/S system of designating chirality, based on the atomic numbers of atoms near the asymmetric carbon, they have R chirality, because of the presence of sulfur or selenium as a second neighbor to the asymmetric carbon. In humans, selenocystine is involved in selenoamino acid metabolism. When cells are grown in the absence of selenium, translation of selenoproteins terminates at the UGA codon, resulting in a truncated, nonfunctional enzyme. Instead, cells store selenium in the less reactive oxidized form, selenocystine, or in methylated form, selenomethionine. Unlike other amino acids present in biological proteins, selenocysteine is not coded for directly in the genetic code. Rather, the tRNA-bound seryl residue is converted to a selenocysteine residue by the pyridoxal phosphate-containing enzyme selenocysteine synthase.
