CapR-Terminator


Characterization

Instruction

CapR is a transcriptional activator which belongs to NtrC family as DmpR. Sequence analysis of both capR gene and CapR protein reveals the significant similarity with DmpR, for their protein sequences are distinct at 9 residues only.

Structure

CapR has four domains. A domain is the signal reception domain, which undergoes conformational change when exposed to proper inducers. B domain is a linker, regulating the relative spatial position of A domain and C domain. C domain is the transcriptional activation domain. D domain contains a helix-turn-helix motif, which is capable of binding DNA sequence on Po promoter.

Fig 1 Structure of CapR protein. From N terminal to C terminal are domain A, domain B, domain C, domain D.


Detection profile

CapR detects phenol and its’ derivatives such as catechol. The detection profile of CapR is widely overlapped with that of DmpR. Previous works showed that when exposed to inducers at the concentration of 100M, CapR’s response to phenol and catechol could reach 300 and 100 fold respectively via firefly luciferin assay.
