Haemoglobin is a paradigm for exploring allosteric regulation, wherein ligand binding at one site induces conformational changes that affect functional activity at a distant site. These structural ...

How proteins evolved the ability to form complexes made up of multiple subunits—and what functions this new structure enabled in early multimeric proteins—isn’t well understood. To better understand ...

ARLINGTON, Va.– Red-blooded genealogists take note: The discovery in microbes of two oxygen-packing proteins, the earliest known ancestors to hemoglobin, brings scientists closer to identifying the ...

Artificial oxygen carriers and haemoglobin‐based therapies represent a rapidly evolving field that seeks to overcome the limitations of conventional blood transfusions. These therapies aim to ...

Hemoglobin helps red blood cells carry oxygen to your muscles and tissues. Abnormal hemoglobin levels can be a sign of several health problems. Hemoglobin is a component of your blood that delivers ...

Webbed feet, flipper-like wings and unique feathers all helped penguins adapt to life underwater. But by resurrecting two ancient versions of hemoglobin, a research team has shown that the evolution ...
