Plant carotenoid cleavage oxygenases: structure-function relationships and role in development and metabolism.

Briefings in Functional Genomics, 2019
A plant communicates within itself and with the outside world by deploying an array of agents that include several attractants by virtue of their color and smell. In this category, the contribution of 'carotenoids and apocarotenoids' is very significant.

Heme Oxygenase and the Kidney

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

1974
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 ...

Bacterial Heme Oxygenases

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, 2015
The 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

Applications of Oxygenases in the Chemoenzymatic Total Synthesis of Complex Natural Products.

Biochemistry, 2017
Nature has produced a diverse range of oxygenases for the modification of secondary metabolites with selectivity profiles that are unmatched by conventional man-made catalysts. In the past two decades, organic chemists have begun to harness the synthetic

The mechanism of heme oxygenase

Current Opinion in Chemical Biology, 2000
Major 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

Analgesia and cyclo-oxygenase inhibitors

Digestive and Liver Disease, 2001
Non-steroidal anti-inflammatory drugs are among the most commonly used medications and they are a mainstay in the treatment of inflammatory diseases. Non-steroidal anti-inflammatory drugs are widely used to reduce pain associated with acute or chronic inflammation.

Oxidases and Oxygenases

2007
An oxidase catalyzes the oxidation of a substrate by O2 without incorporating an oxygen atom into the product. A monooxygenase catalyzes oxidation by O2 with incorporation of one oxygen atom into the product, and oxidation by a dioxygenase proceeds with incorporation of both atoms of O2 into the product.
