WebJan 22, 2024 · Bacterial tryptophanase is responsible for the conversion of 5-hydroxytryptophan. Since 5-HI is a structural analogue of indole, which is produced by bacterial degradation of L-tryptophan via TnaA enzyme, we hypothesized that 5-HTP is also a substrate for the TnaA enzyme (28) . To verify our hypothesis, E. WebIn bacteria, translation is coupled with transcription, meaning ribosomes begin synthesizing peptides chain (translation) as soon as transcription of that gene (an mRNA) starts. Translation can affect the structure of the growing RNA chain. Stem-loop structures are formed for terminating the transcription depending upon the level of tryptophan. WebIn bacteria, related genes are often found in a cluster on the chromosome, where they are transcribed from one promoter (RNA polymerase binding site) as a single unit. ...
