Catabolic transposons

Biodegradation, 1994
The structure and function of transposable elements that code for catabolic pathways involved in the biodegradation of organic compounds are reviewed. Seven of these catabolic transposons have structural features that place them in the Class I (composite) or Class II (Tn3-family) bacterial elements. One is a conjugative transposon.

Surfactant catabolism

Respirology, 2006
Abstract:  Alveolar pulmonary surfactant is a complex of macromolecular aggregates composed of phospholipids and surfactant proteins (SP) that is essential for maintenance of normal lung function. The importance of surfactant homeostasis is recognized in the patients and the animal models with pulmonary disease, although the mechanisms of surfactant ...

Bacterial catabolism of nicotine: Catabolic strains, pathways and modules

Environmental Research, 2020
Nicotine, the major alkaloid in tobacco, is a toxic, carcinogenic, and addictive compound. In recent years, nicotine catabolism in prokaryotes, including the catabolic pathways for its degradation and the catabolic genes that encode the enzymes of these pathways, have been systemically investigated. In this review, the three known pathways for nicotine

Prostaglandin catabolizing enzymes

Prostaglandins & Other Lipid Mediators, 2002
The primary catabolic pathway of prostaglandins and related eicosanoids is initiated by the oxidation of 15(S)-hydroxyl group catalyzed by NAD+-dependent 15-hydroxyprostaglandin dehydrogenase (15-PGDH) followed by the reduction of delta13 double bond catalyzed by NADPH/NADH dependent delta13-15-ketoprostaglandin reductase (13-PGR).

Catabolic proinflammatory cytokines

Current Opinion in Clinical Nutrition and Metabolic Care, 1998
Catabolic proinflammatory cytokines play a key role in mediating biochemical changes associated with many pathophysiological states. The present review emphasizes the role of this type of cytokine in inflammation and cachexia. Additionally, it reviews the role of one of these mediators in the induction of insulin resistance by dealing with some of the ...

Bacterial catabolic transposons

Applied Microbiology and Biotechnology, 1999
The introduction of foreign organic hydrocarbons into the environment in recent years, as in the widespread use of antibiotics, has resulted in the evolution of novel adaptive mechanisms by bacteria for the biodegradation of the organic pollutants. Plasmids have been implicated in the catabolism of many of these complex xenobiotics. The catabolic genes

Catabolism of polyamines

Amino Acids, 2004
Owing to the establishment of cells and transgenic animals which either lack or over-express acetylCoA:spermidine N(1)-acetyltransferase a major progress was made in our understanding of the role of polyamine acetylation. Cloning of polyamine oxidases of mammalian cell origin revealed the existence of several enzymes with different substrate and ...
