Protein
HTH-type transcriptional regulator TdfR
Organism
Cupriavidus necator (strain JMP 134 / LMG 1197)
Function
Involved in the regulation of 3-chlorocatechol degradation. Transcriptional regulator of tfdB expression. Acts as a repressor in the absence of its effector (either 2-cis-chlorodiene lactone or chloromaleylacetate) but acts as an activator when its effector is present.
Similarity
Belongs to the LysR transcriptional regulatory family.
