Cross-database IDs: Link
Organism: Cyanobacteria (e.g. Synechococcus elongatus (strain PCC 7942) (Anacystis nidulans R2))Location: Chromosome
Compound: Zinc (Zn)Description: Repressor protein smtB; regulates the metallothionein synthesis in transcrition level negatively; its a helix-turn-helix protein in the same family of arsR and cadC; binds at imperfect inverted repeat TGAAACA-GT-TATTCA between the transcription initiation site and the ribosome binding site for smtA; Transcriptional repressor of the Expression of the smtA gene. Binds two zinc ions per dimer. The complex of DNA and smtB is dissociated by zinc ions.
