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 ...

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 ...

Iron and oxygen work hand in hand to keep your body energized and alive. Iron forms the core of hemoglobin, the protein that carries oxygen from your lungs to every cell. Understanding how your body ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 95, No. 26 (Dec. 22, 1998), pp. 15177-15182 (6 pages) The FixL proteins are biological oxygen sensors that ...

Heme is a coordination complex consisting of a porphyrin ring surrounding a single ferrous (Fe 2+) or ferric (Fe 3+) ion, able to bond with diatomic oxygen and transport it around the body. Four heme ...

New research has shown that the production of heme, a blood molecule, supports the progression of acute myeloid leukemia, which is an aggressive form of blood cancer. Researchers say that suppressing ...
