Heme proteins play essential roles in biology, but little is known about heme transport inside mammalian cells or how heme is inserted into soluble proteins. We recently found that nitric oxide (NO) ...

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 ...

It took an unlikely food innovation -- earth-friendly vegetarian patties, made to taste and "bleed" like the familiar meaty ones -- to make people aware of heme. But heme is an essential part of ...

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 ...
