WebQuestion: Usually, bacteria only make tryptophan when tryptophan is absent or available in low concentration. However, a particular bacterial mutation makes tryptophan all the time whether or not tryptophan is present. What could explain this phenotype? the antiterminator hairpin is unable to form the terminator hairpin is unable to form trpe is mutated trpA is WebWhen the tryptophan concentration is low, the ribosome stalls at these codons, which leads to the formation of the anti-terminator hairpin. Thus, when tryptophan is needed, the RNAP does not terminate, the trp operon is expressed, and tryptophan is synthesized. Conversely, transcription of the trp operon is prevented when more tryptophan is not ...

The leader sequence can form two different structures known as the terminator and the anti-terminator, based on the Tryptophan amounts in the cell. The leader also codes for very short peptide sequence that is rich in tryptophan. The terminator structure is recognised as … hoitotakuu hammashoitoWeb3 Figure S3.
