Transport of Oxygen during Hibernation: the Hemoglobin of Dryomys nitedula
Oxygen transport proteins might well represent an interesting model which can be used to evaluate the different strategies adopted by evolution to solve the problem of oxygen supply in accordance with the physiological requirements of the specific tissues of a given organism. This is clearly demonstrated by various mammalian hemoglobins which have developed a number of complex regulatory mechanisms involving binding with allosteric effectors (such as organic phosphates, CO2, chloride ions and Bohr protons) and their interplay with temperature.
