Ultrafast dynamics of heme distortion in the O2-sensor of a thermophilic anaerobe bacterium

Dioxygen protein sensors undergo structural distortions upon binding, but the role of heme distortion in allostery is unclear. Here heme distortion in a bacterial dioxygen sensor is studied using picosecond time-resolved electronic absorption spectroscopy and shown to control the allosteric equilibr...
