The heme oxygenase system: a regulator of second messenger gases.
Annual Review of Pharmacology and Toxicology, 1997The heme oxygenase (HO) system consists of two forms identified to date: the oxidative stress-inducible protein HO-1 (HSP32) and the constitutive isozyme HO-2. These proteins, which are different gene products, have little in common in primary structure,

Heme oxygenase-1/carbon monoxide: from basic science to therapeutic applications.
Physiological Reviews, 2006The heme oxygenases, which consist of constitutive and inducible isozymes (HO-1, HO-2), catalyze the rate-limiting step in the metabolic conversion of heme to the bile pigments (i.e., biliverdin and bilirubin) and thus constitute a major intracellular ...

Endocannabinoids and their oxygenation by cyclo-oxygenases, lipoxygenases and other oxygenases
Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2015The naturally occurring mammalian endocannabinoids possess biological attributes that extend beyond interaction with cannabinoid receptors. These extended biological properties are the result of oxidative metabolism of the principal mammalian endocannabinoids arachidonoyl ethanolamide (anandamide; A-EA) and 2-arachidonoylglycerol (2-AG).

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.

2-Oxoglutarate-Dependent Oxygenases [PDF]
Annual Review of Biochemistry, 2018 2-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.

Publisher Summary This chapter reviews the reaction mechanisms of iron-containing oxygenases with a special emphasis on the role of iron in the function and structure of oxygenases. The role of iron in oxygenases has been assumed to be a site of oxygen activation but also appears to be closely related to the substrate binding site, although the ...

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

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
