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 …

The heme prosthetic group in hemoglobins is most often attached to the globin through
coordination of either one or two histidine side chains. Those proteins with one histidine …

The functional properties of a protein primarily depend on its three-dimensional (3D)
structure. These properties have classically been assigned, visualized and analysed on the …

For a long time, respiratory proteins have been considered unnecessary in most insects
because the tracheal system was thought to be sufficient for oxygen supply. Only a few …

Carbon monoxide (CO) is a leading cause of poisoning deaths worldwide, with no available
antidotal therapy. We introduce a potential treatment paradigm for CO poisoning, based on …

The evolution of oxygen transport hemoglobins occurred on at least two independent
occasions. The earliest event led to myoglobin and red blood cell hemoglobin in animals. In …

We investigated the intrinsic strength of distal and proximal FeN bonds for both ferric and
ferrous oxidation states of bishistidyl hemoproteins from bacteria, animals, human, and …

Respiratory proteins enhance the capacity of the blood for oxygen transport and support
intracellular storage and delivery of oxygen. Hemocyanin and hemoglobin are the …

Chironomidae species are universally used for studying the impact of pollutants in aquatic
systems. The nonbiting midge Propsilocerus akamusi is often found in urban streams and is …

Proteins are sensitive to temperature, and abrupt changes in the normal temperature
conditions can have a profound impact on both structure and function, leading to protein …
