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

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 ...

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 ...

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

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;

Bacterial catabolic transposons
Applied Microbiology and Biotechnology, 1999The 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

Catabolic Insufficiency and Aging
Annals of the New York Academy of Sciences, 2006Abstract: Cellular degradative processes, which include lysosomal (autophagic) and proteasomal degradation, as well as the activity of cytosolic and mitochondrial proteases, provide for a continuous turnover of damaged and obsolete biomolecules and organelles.
