WebA DNA sequence called the operator sequence is encoded between the promoter region and the first trp-coding gene. This operator contains the DNA code to which the repressor protein can bind. When tryptophan is present in the cell, two tryptophan molecules bind to the trp repressor, which changes shape to bind to the trp operator.

WebE. coli can synthesize tryptophan using enzymes that are encoded by five structural genes located next to each other in the trp operon (Figure 13.2). When environmental tryptophan is low, the operon is turned on. This means that transcription is initiated, the genes are expressed, and tryptophan is synthesized. Web5.2.4 Tryptophan synthase. Bacterial tryptophan synthase is an example of an oligomeric enzyme which contains two different functional sub-units. The enzyme catalyses the reaction: (5.2) It can be dissociated into two α sub-units, each of molecular weight 29 000, and a β 2 sub-unit, of molecular weight 90 000.
