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.
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]

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.
Later studies proposed that the reaction involves a condensation process, where glyoxylic acid combines with the indole group of tryptophan to form a complex quinonoid structure. This process explains the strong color change observed in the test and has been key to understanding tryptophan's chemical properties and its function in proteins.
Attenuators may be classified according to the type of molecule which induces the change in RNA structure. It is likely that transcription-attenuation mechanisms developed early, perhaps prior to the archaea/bacteria separation and have since evolved to use a number of different sensing molecules (the tryptophan biosynthetic operon has been found to use three different mechanisms in different ...
Tryptophan-rich sensory proteins (TspO) are a family of proteins that are involved in transmembrane signalling. In either prokaryotes or mitochondria they are localized to the outer membrane , and have been shown to bind and transport dicarboxylic tetrapyrrole intermediates of the haem biosynthetic pathway .
