Scientists at Washington University in St. Louis described for the first time the structure of a bifunctional protein, called CcsBA, that transports heme and attaches it to cytochromes. Credit: Kranz ...

One of the greatest challenges with lithium-oxygen batteries involves identifying catalysts that facilitate the growth and evolution of cathode species on an oxygen electrode. Heterogeneous solid ...

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 ...

Scientists at the University of Saskatchewan College of Medicine, Department of Physiology, Saskatoon, Canada, led by Dr. Joseph Fomusi Ndisang have determined that upregulating heme-oxygenase with ...

Scientists have long been puzzled by how maturing red blood cells manage to produce all the hemoglobin they need to carry ...

Symbiotic relationships between legumes and the bacteria that grow in their roots are critical for plant survival. Without those bacteria, the plants would have no source of nitrogen, an element that ...

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 ...

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 ...
