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 ...

Catabolism of strigolactones by a carboxylesterase
Nature Plants, 2021Strigolactones (SLs) are carotenoid-derived plant hormones that control shoot branching and communications between host plants and symbiotic fungi or root parasitic plants. Extensive studies have identified the key components participating in SL biosynthesis and signalling, whereas the catabolism or deactivation of endogenous SLs in planta remains ...

Bacterial catabolism of nicotine: Catabolic strains, pathways and modules
Environmental Research, 2020Nicotine, 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

Purine catabolism by enterobacteria
2023Purines are abundant among organic nitrogen sources and have high nitrogen content. Accordingly, microorganisms have evolved different pathways to catabolize purines and their metabolic products such as allantoin. Enterobacteria from the genera Escherichia, Klebsiella and Salmonella have three such pathways.

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 ...

Prostaglandin catabolizing enzymes
Prostaglandins & Other Lipid Mediators, 2002The 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).

The Journal of laboratory and clinical medicine, 1976
The catabolic site(s) of plasma lipoproteins and apolipoproteins has not been established. We have purified one of the major apolipoproteins and explored its catabolic rate and its site of catabolism. Apolipoprotein (Apo) A-1 was purified by column chromatography of canine high-density lipoprotein (HDL) subfraction, HDL3, which was totally delipidated;

The role of IGFs in catabolism
Baillière's Clinical Endocrinology and Metabolism, 1997The hypercatabolic response to trauma, extensive surgery and sepsis is characterized by an increased metabolic rate, severe muscle wasting and a negative nitrogen balance. This process of 'autocannibalism' may be in part a consequence of a disordered growth hormone (GH)/insulin-like growth factor (IGF) axis. In this chapter the normal physiology of the

Catabolic proinflammatory cytokines
Current Opinion in Clinical Nutrition and Metabolic Care, 1998Catabolic 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 ...
