New Marker of Colon Cancer Risk Associated with Heme Intake: 1,4-Dihydroxynonane Mercapturic Acid [PDF]
, 2006 Background: Red meat consumption is associated with an increased risk of colon cancer. Animal studies show that heme, found in red meat, promotes preneoplastic lesions in the colon, probably due to the oxidative properties of this compound.

Control of intracellular heme levels: Heme transporters and heme oxygenases
Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2011 Heme serves as a co-factor in proteins involved in fundamental biological processes including oxidative metabolism, oxygen storage and transport, signal transduction and drug metabolism. In addition, heme is important for systemic iron homeostasis in mammals.

Import of cytochrome c into mitochondria [PDF]
, 1987 The import of cytochrome c into mitochondria can be resolved into a number of discrete steps. Here we report on the covalent attachment of heme to apocytochrome c by the enzyme cytochrome c heme lyase in mitochondria from Neurospora crassa. A new method

Heme iron from meat and risk of colorectal cancer: a meta-analysis and a review of the mechanisms involved [PDF]
, 2011 Red meat and processed meat intake is associated with a risk of colorectal cancer, a major cause of death in affluent countries. Epidemiological and experimental evidence supports the hypothesis that heme iron present in meat promotes colorectal cancer ...

Oxygen Activation and Radical Transformations in Heme Proteins and Metalloporphyrins
Chemical Reviews, 2017 As a result of the adaptation of life to an aerobic environment, nature has evolved a panoply of metalloproteins for oxidative metabolism and protection against reactive oxygen species. Despite the diverse structures and functions of these proteins, they

Heme Oxygenase-2 Is a Hemoprotein and Binds Heme through Heme Regulatory Motifs That Are Not Involved in Heme Catalysis [PDF]
Journal of Biological Chemistry, 1997 The heme oxygenase (HO) system degrades heme to biliverdin and CO and releases chelated iron. In the primary sequence of the constitutive form, HO-2, there are three potential heme binding sites: two heme regulatory motifs (HRMs) with the absolutely conserved Cys-Pro pair, and a conserved 24-residue heme catalytic pocket with a histidine residue ...

Regulation of nitric oxide signaling by formation of a distal receptor-ligand complex. [PDF]
, 2017 The binding of nitric oxide (NO) to the heme cofactor of heme-nitric oxide/oxygen binding (H-NOX) proteins can lead to the dissociation of the heme-ligating histidine residue and yield a five-coordinate nitrosyl complex, an important step for NO ...
