Method: X-ray diffraction, Resolution 2.56Å Ligands: HG Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function Q799U3_PRIMG Mediates the mercuric-dependent induction of mercury resistance operon. In the absence of mercury MerR represses transcription by binding tightly to the mer operator region; when mercury is present the dimeric complex binds a single ion and becomes a potent transcriptional activator, while remaining bound to the mer site.[ARBA:ARBA00024874] See Also Transcriptional activator 3D structures
