Characterization of a globin-coupled oxygen sensor with a gene-regulating function.

Globin-coupled sensors (GCSs) are multiple-domain transducers, consisting of a regulatory globin-like heme-binding domain and a linked transducer domain(s). GCSs have been described in both Archaea and bacteria. They are generally assumed to bind O(2) (and perhaps other gaseous ligands) and to transmit a conformational change signal through the transducer… CONTINUE READING
