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.
