FACTORS AFFECTING ASPARTASE ACTIVITY

Factors affecting aspartase activity.

Depue, Robert H. (Hahnemann Medical College, Philadelphia), and Albert G. Moat. Factors affecting aspartase activity. J. Bacteriol. 82:383-386. 1961.-Cells of Escherichia coli grown in a glucose-mineral salts medium contain about one-fifth the amount of aspartase activity observed in cells grown in a yeast extract-peptone medium. The aspartase activity of the cells grown in glucose-salts medium...

Factors affecting the activity of phenolic disinfectants.

Low challenge phenol coefficient and high challenge use-dilution tests were made on a neutral cocoanut oil soap emulsion of o-phenylphenol and aqueous solutions of sodium o-phenylphenate prepared in the laboratory from the phenol using a stoichiometric amount of NaOH as well as with increasing amounts of excess NaOH. The phenol had considerably greater activity in both test methods when emulsif...

Factors affecting cytochrome P-450 3A activity in cancer patients.

PURPOSE The purpose is to identify the demographic, physiologic, and inheritable factors that influence CYP3A activity in cancer patients. EXPERIMENTAL DESIGN A total of 134 patients (62 females; age range, 26 to 83 years) underwent the erythromycin breath test as a phenotyping probe of CYP3A. Genomic DNA was screened for six variants of suspected functional relevance in CYP3A4 (CYP3A4*1B, CY...

Endogenous and exogenous factors affecting lipoprotein lipase activity

Factors affecting the activity of mitochondrial and soluble aconitase.

Considerable information on the intracellular localization of enzymes has been obtained in recent years through the technique of differential centrifugation of sucrose homogenates of tissues and subsequent testing of the fractions for enzyme activity. One of the results of this work has been the demonstration that rat liver mitochondria (Mw) are capable of completely oxidizing a wide variety of...
