how haemoglobin acts as an allosteric protein?
Answer Posted / pallavi kushwaha
Allosteric proteins are the protein whose shape is changed
when it binds to a particular molecule and in it's new
shape the protein ability to react a second molecule also
changed.In case of hemoglobin, in deoxyhemoglobin the
globin molecule are tightly bound in tense(T)
configurationand having very less affinity for oxygen. When
oxygen is first bound, configuration of hemoglobin
changed,bond holding the globin units are
released,producing a relaxed(R) configuration which exposes
more oxygen binding site.thus it acts as allosteric
protein, this interactive binding phenomenon is also termed
cooperativity.
