WebSep 26, 2024 · A collection of genes that are transcribed together encode the components for tryptophan synthesis. The E. coli trp operon is a cluster of genes that code for biosynthetic enzymes for the amino acid tryptophan. When tryptophan levels are low, the trp operon is expressed (turned “on”) and when they are high, it is repressed (turned “off”). WebL-Tryptophan is degraded via oxidative cleavage of the C-2,C-3 bond, to give N-formyl-kynurenine, as shown in Figure 25.Tryptophan 2,3-dioxygenase (TDO), found in mammals and bacteria, is selective for cleavage of tryptophan, whereas indoleamine 2,3-dioxygenase (IDO), found only in mammals, is able to cleave other indoleamine derivatives such as …
