Abstract: | This review briefs the modern concepts of the diversity of hemoglobin functions. The hemoglobins discovered in the representatives
of all kingdoms of living nature are described. Specific structural features of various groups of these proteins, including
flavohemoglobins and truncated hemoglobins, are discussed. The transport, catalytic, and sensory functions of these proteins
are described as well as their roles in oxidative, nitrosative, and carbonyl stresses and the changes in their functions caused
by modifications of the molecule. The issues of hemoglobin origin and evolution are discussed. |
