Structural highlights
FunctionTOXR_VIBCH This transcription activator controls cholera toxin, pilus colonization factor and outer membrane protein expression in V.cholerae. It binds to the 5'-TTTTGAT-3' tandemly repeated DNA sequence in the cholera toxin promoter region. ToxS interacts with the C-terminal periplasmic domain of ToxR, stimulating its activity. It activates transcription at the promoters for tcpI and tcpA and this is presumably via ToxT. See Also |
