Hemoglobin functions as a tetrameric oxygen carrier whose capacity to bind and release oxygen hinges on allosteric transitions between tense (T) and relaxed (R) quaternary states. A network of ...
In Gram-positive bacteria, sophisticated machineries to acquire the heme group of hemoglobin (Hb) have evolved to extract the precious iron atom contained in it. In the human pathogen Streptococcus ...
The evolution of biomedical science can be appreciated through studies of hemoglobin, the oxygen-carrying protein in red cells. Before molecular cloning, the geneticist Arno Motulsky noted, “Many ...
