KnowraSelenocysteineLinked fromLinked fromThe 7 pages that link to Selenocysteine, each with the reason it gives.All 7Broader topic 3Related 1Compared with 3Amino acidBroader topic: It is a rare exception to the usual set of 20 standard amino acids.Genetic codeBroader topic: It demonstrates that a stop codon can specify an amino acid in a defined context.CysteineCompared with: It is a rare amino acid analogue with distinct genetic encoding and chemical reactivity.SeleniumRelated: Its recognition established selenium as a biologically used element rather than only a toxin.Proteinogenic amino acidBroader topic: It is a specialized proteinogenic amino acid beyond the canonical set of 20.SerineCompared with: It contrasts with serine’s ordinary genetic encoding and oxygen-bearing side chain.PyrrolysineCompared with: It is the earlier natural example of recoding a stop codon to insert an amino acid.
