Researchers described for the first time the structure of a bifunctional protein, called CcsBA, that transports heme and attaches it to cytochromes. The study captured two conformational states of ...

The hemoglobin in the red blood cells ensures that our body cells receive sufficient oxygen. When the blood pigment is broken down, 'heme' is produced, which in turn can influence the protein cocktail ...

Heme is an essential part of the protein hemoglobin, which colors human blood red. Heme also is crucial for cytochrome proteins, which power the cell. Humans, animals, plants and bacteria all use heme ...
