This amino acid is unusually brominated in a peptide found in the venom of marine cone snails.
This amino acid is unusually brominated in a peptide found in the venom of marine cone snails.Plant auxins are synthesized from this amino acid, which through a kynurenine intermediate is theprecursor of niacin. High levels of this substance cause the formation of a 3-4 stem loop and allowsthe complete translation of a leader peptide, which in turn allows synthesis of a polycistronic RNAfrom genes A through E of its namesake repressible (*) operon. Its hydroxylation is the first step in thesynthesis of serotonin. This amino acid is coded for by only one codon, UGG, and has a very bulky,aromatic indole side chain. For 10 points, name this amino acid symbolized W, which is often incorrectlyassumed to be responsible for turkey-induced drowsiness.
