Post-transcriptional regulation of aromatic amino acid metabolism by GcvB small RNA in .

synthesizes aromatic amino acids (AAAs) through the common pathway to produce the precursor, chorismate, and the three terminal pathways to convert chorismate into Phe, Tyr, and Trp. also imports exogenous AAAs through five transporters. GcvB small RNA post-transcriptionally regulates more than 50 genes involved in amino acid uptake and biosynthesis in , but the full extent of GcvB regulon is still underestimated.
