Ligand‐ and proton‐linked conformational changes of the ferrous 2/2 hemoglobin of Pseudoalteromonas haloplanktis TAC125

The spectroscopic and ligand‐binding properties of a 2/2 globin from the Antarctic bacterium Pseudoalteromonas haloplanktis TAC125 have been studied in the ferrous state. It displays two major conformations characterized by CO‐association rates that differ by a factor of 20, with relative fractions...
