Hemoglobin (Hb), the paradigm for allosteric proteins through decades, has gained
renaissance in recent years following discovery of globins or their genes in all living …

The recognition of the important role of the polar habitats in global climate changes has
awakened great interest in the evolutionary biology of polar organisms. They are exposed to …

Expression of multiple hemoglobin isoforms with differing physiochemical properties likely
helps species adapt to different environmental and physiological conditions. Antarctic …

Antarctic fish of the family Nototheniidae usually have a single major hemoglobin (Hb 1),
often a second, minor component (Hb 2, about 5% of the total), and traces of another …

Analysis of the molecular properties of proteins extracted from organisms living under
extreme conditions often highlights peculiar features. We investigated by UV‐visible …

The functional and structural basis for the Root effect has been investigated in the anodic
hemoglobin of the European eel, Anguilla anguilla. This hemoglobin exhibits a large Bohr …

The Arctic fish Anarhichas minor, a benthic sedentary species, displays high hemoglobin
multiplicity. The three major hemoglobins (Hb 1, Hb 2, and Hb 3) show important functional …

The Arctic and Antarctic marine faunas differ by age and isolation. Fishes of the two polar
regions have undergone different regional histories that have driven the physiological …

Spontaneous autoxidation of tetrameric Hbs leads to the formation of Fe (III) forms, whose
physiological role is not fully understood. Here we report structural characterization by EPR …

Considering the variety of species that depend on hemoglobin for oxygen transport, these
molecules must execute their primary function under extreme environmental conditions …
