Pyrrolysine

WebJan 16, 2007 · Pyrrolysine has entered natural genetic codes by the translation of UAG, a canonical stop codon. UAG translation as pyrrolysine requires the pylT gene product, an amber-decoding tRNA Pyl that is aminoacylated with pyrrolysine by the pyrrolysyl-tRNA synthetase produced from the pylS gene. The pylTS genes form a gene cluster with … WebOct 5, 2024 · #22 Pyrrolysine. Selenocysteine takes a chemical detour to be smuggled into proteins via serine and plays somewhat of an outsider role compared to the “magic twenty”. This is completely not the case for amino acid #22, pyrrolysine. This amino acid (abbreviated Pyr) remained fully unknown until 2002.
