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.

Comparative Biochemistry and Physiology, 1968
Abstract 1. 1. In turtles and caimans, histidine injection increased glutamine in all tissues examined. In the turtle, histidine injection produced a rise in liver citrulline. 2. 2. Since neither citrulline nor glutamine was labeled after injection of C 14 -histidine, the carbon chains of these derivatives were not derived from histidine. 3.

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
