Pine, Martin J. (Roswell Park Memorial Institute, Buffalo, N.Y.). Metabolic control of intracellular proteolysis in growing and resting cells of Escherichia coli. J. Bacteriol. 92:847-850. 1966.-Protein breakdown was examined in Escherichia coli under varying conditions of growth and during nutritional deprivation. Optimal breakdown rates, estimated over short time periods of protein synthesis and decay, are invariant and unrepressible by any condition of growth or starvation. A more important aspect of metabolic control is manifest in the selection imposed by the physiological state of the cell for breakdown of limited populations of proteins. During the progress of growth, one-half to three-quarters of the protein susceptible in the resting state is progressively spared, and breakdown is continued in populations that are more selected and more frequently regenerated.

D002247	Carbon Isotopes	Stable carbon atoms that have the same atomic number as the element carbon but differ in atomic weight. C-13 is a stable carbon isotope.	Carbon Isotope,Isotope, Carbon,Isotopes, Carbon
D004926	Escherichia coli	A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.	Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli
