DNA and Cell Biology, 2002
Heme plays a significant pathogenic role in several diseases involving the kidney. The cellular content of heme, derived either from the delivery of filtered heme proteins such as hemoglobin and myoglobin, or from the breakdown of ubiquitous intracellular heme proteins, is regulated via the heme oxygenase enzyme system.

Oxygenases, Thwarted Oxygenases, and Oxygen-dependent Halogenases
2022Oxygenases, both flavin-dependent and iron-dependent, act on all classes of natural products, often late in scaffold maturation, to introduce oxygen functional groups, including hydroxyl and epoxide groups. The hydroxyl groups then function as nucleophiles for alkylations, acylations, and glycosylations.

Heme oxygenase-1 and heme oxygenase-2 expression in bruises
Forensic Science, Medicine, and Pathology, 2015The first step in catabolism of hemoglobin in a bruise is performed by the enzyme heme oxygenase, which produces biliverdin that is then reduced to bilirubin. The development of yellow coloration in bruises can be attributed to local accumulation of degradation products of hemoglobin, including bilirubin, but it is not clear why there is a delay before

Antioxidants & Redox Signaling, 2004
The importance of heme oxygenases in heme catabolism, iron utilization, and cellular signaling has been recognized for many years and is a well studied process in eukaryotes. Through the accessibility of an increasing number of bacterial genomes, it has become evident that heme oxygenases are also widespread in prokaryotes. In these organisms, the heme

2-Oxoglutarate-Dependent Oxygenases
Annual Review of Biochemistry, 20182-Oxoglutarate (2OG)-dependent oxygenases (2OGXs) catalyze a remarkably diverse range of oxidative reactions. In animals, these comprise hydroxylations and N-demethylations proceeding via hydroxylation; in plants and microbes, they catalyze a wider range including ring formations, rearrangements, desaturations, and halogenations.

The mechanism of heme oxygenase
Current Opinion in Chemical Biology, 2000Major advances have been made in determining the structure of heme oxygenase and the relationship between its structure and catalytic activity. The nature of the first step in the reaction sequence, heme alpha-meso-hydroxylation, is now clear, although the mechanisms that control the alpha-regiospecificity remain elusive. Hypothetical mechanisms can be

Oxidoreductases and Oxygenases
1984Oxidoreductases (dehydrogenases or oxidases) catalyze the addition or the removal of hydrogen or electrons. Oxygenases bring about the incorporation of oxygen which originates from molecular oxygen.
