Haemoglobin (Hb) is widely known as the iron-containing protein in blood that is essential
for O 2 transport in mammals. Less widely recognised is that erythrocyte Hb belongs to a …

Heme-copper oxidases (HCOs) are terminal enzymes on the mitochondrial or bacterial

Neuroglobin, mainly expressed in vertebrate brain and retina, is a recently identified
member of the globin superfamily. Augmenting O 2 supply, neuroglobin promotes survival of …

Neuroglobin and cytoglobin reversibly bind oxygen in competition with the distal histidine,
and the observed oxygen affinity therefore depends on the properties of both ligands. In the …
