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 is essential for cellular function, as it is required for oxygen transport and mitochondria oxidative respiration. However, uncoordinated regulation of ...

Heme degradation plays important biological roles, ranging from generating light-absorbing compounds in plants to facilitating iron homeostasis in mammals. The X-ray crystal structure of human heme ...

Your body absorbs heme iron from meat, fish, and poultry more easily than non-heme iron from plant foods. Heme iron is absorbed at rates up to 40%, while non-heme iron is absorbed much less ...

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 ...
