A domain that contains a pair of these amino acids spaced 20 residues apart is called the rsp5-domain and binds to proline-rich motifs. This compounds namesake synthase contains tunnels between its alpha and beta active sites in a classic example of substrate channelling. In mammalian mitochondria, the UGA codon isn't a stop codon, but codes for this amino acid. This amino acid has the strongest absorbance at 280 nm, which is why that absorbance is used to track protein folding. This amino acid is unusually only encoded by one codon, (*) UGG. The cluster of genes synthesizing this compound is activated by a stall in the synthesis of a leader peptide and contains A through E structural genes; that mechanism is attenuation. It serves as the precursor to niacin and serotonin, the latter through its namesake hydroxylase. For 10 points, name this amino acid with an indole side chain and one-letter symbol W.
