Gene(s): | aroH Genome Browser M3D Gene expression COLOMBOS | |||||||||
Note(s): | There is a putative CRP-binding site between the aroHp1 and the aroHp2 promoters, but this protein did not demonstrate any effect on the promoters Hudson GS,1991 The trpLEDCBA, aroH, and trpR operons are coordinately regulated by the TrpR transcriptional repressor in response to intracellular levels of L-tryptophan (Kumamoto AA,1987and references therein). TrpR acts differently at each operator and binds to multiple helically stacked sites Kumamoto AA,1987 The expression of the gene aroH is enhanced under oxygen limitation Kawaguchi H, Miyagawa H, Nakamura-Tsuruta S, Takaya N, Ogino C, Kondo A,2019. |
