Tryptophan ball and stick model spinning. Tryptophan (symbol Trp or W) [3] is an α-amino acid that is used in the biosynthesis of proteins.Tryptophan contains an α-amino group, an α-carboxylic acid group, and a side chain indole, making it a polar molecule with a non-polar aromatic beta carbon substituent.
Tryptophan synthase or tryptophan synthetase is an enzyme (EC 4.2.1.20) that catalyzes the final two steps in the biosynthesis of tryptophan. [1] [2] It is commonly found in Eubacteria, [3] Archaebacteria, [4] Protista, [5] Fungi, [6] and Plantae. [7] However, it is absent from Animalia. [8] It is typically found as an α2β2 tetramer.
Structure of the trp operon. The trp operon is a group of genes that are transcribed together, encoding the enzymes that produce the amino acid tryptophan in bacteria. The trp operon was first characterized in Escherichia coli, and it has since been discovered in many other bacteria. [1]
Protein primary structure is the linear sequence of amino acids in a peptide or protein. [1] By convention, the primary structure of a protein is reported starting from the amino -terminal (N) end to the carboxyl -terminal (C) end.
SST treats any assignment of secondary structure as a potential hypothesis that attempts to explain given protein coordinate data. The core idea is that the best secondary structural assignment is the one that can explain ( compress ) the coordinates of a given protein coordinates in the most economical way, thus linking the inference of ...

L-Tryptophan to tryptamine – a trace amine neuromodulator; 5-HTP to serotonin (5-hydroxytryptamine) – a neurotransmitter; However, some of these reactions do not seem to bear much or any biological significance. For example, histamine is biosynthesised strictly via the enzyme histidine decarboxylase in humans and other organisms. [10] [11]
