Carbon monoxide (CO) poisoning leads to 50,000–100,000 emergency room visits and
1,500–2,000 deaths each year in the United States alone. Even with treatment, survivors …

FixL is an oxygen-sensing heme-PAS protein that regulates nitrogen fixation in the root
nodules of plants. In this paper, we present the first photothermal studies of the full-length …

The development of a heme-responsive biosensor for dynamic pathway regulation in
eukaryotes has never been reported, posing a challenge for achieving the efficient synthesis …

The MHYT domain, identified over two decades ago for its potential to detect diatomic gases
like CO, O2 or NO, has awaited experimental validation as a protein sensory domain. Here …

Cells have evolved intricate mechanisms for recognizing and responding to changes in
oxygen (O 2) concentrations. Here, we have reprogrammed cellular hypoxia (low O 2) …

The terminal oxidases of bacterial aerobic respiratory chains are redox-active electrogenic
enzymes that catalyze the four-electron reduction of O2 to 2H2O taking out electrons from …

A diverse array of microorganisms found in oceans, soils, and freshwater environments
utilize carbon monoxide (CO) as a source of energy and/or carbon. 1, 2 To regulate …
