enzyme activity
Baseline enzyme activity is characterized by significant individual variations in both animals and humans.
      
The groups of sprinters and marathoners had a decreased enzyme activity compared to nonathletes (p >amp;lt; 0.05).
      
Lipid Peroxidation and Antioxidant Enzyme Activity in Response to Interval Hypoxic Training
      
In all subjects, the oxidative stress markers decreased and the enzyme activity increased in four days after the IHT course.
      
The enzyme activity strongly depended on exogenous Mg2+ and declined in the presence of EDTA.
      
The rate of enzyme accumulation in the culture liquid increased as the growth rate of the bacterium decreased, so that the maximum enzyme activity was observed in the stationary growth phase.
      
The effect of some intermediates of the citric acid cycle and nucleotides on the enzyme activity was studied.
      
Enzyme activity was detected in polyacrylamide gel after the electrophoresis of cell-free extracts.
      
The enzyme activity in the medium containing xylan or methyl β-xyloside was 1.0 and 1.5 U/ml, respectively; this production level is similar to that achievable at the β-xylosidase production by mycelial fungi.
      
The changes in the hydrophilic-lipophilic balance of the lipase surface significantly affect the character of the regulation of enzyme activity due to changes in the surfactant concentration (the number of micelles).
      
The thermophilic nature of AfLon protease was found to be due to the special features of the enzyme activity regulation, the structure of ATPase domain, and the quaternary structure.
      
When these cells were treated with air oxygen for 40 min, hydrogen peroxide and iron sulfate (II) enhanced oxygen biostimulating effect via stimulation of antioxidant enzyme activity and inhibition of lipid peroxidation.
      
When the time of seed treatment with ionized air was increased to 80 min, lipid peroxidation was activated, antioxidant enzyme activity was inhibited, and the yield of chromosomal aberration increased in seedlings.
      
The accumulation of TBA(thiobarbituric acid)-reactive products was shown to be related to a decrease in antioxidant enzyme activity and an increase in the yield of chromosomal aberrations.
      
Variability of β-glucuronidase enzyme activity was shown in original transgenic plants or among progenies of the first generation in both groups.
      
In T1 progenies of plant 16.40, carrying a duplication of the uidA gene, a drastic decrease in enzyme activity was observed, which correlated with a decrease or absence of mRNA transcripts, pointing to a disturbance in reporter gene expression.
      
The isozyme spectrum of leucine aminopeptidase is presented as a single zone of enzyme activity controlled by one gene.
      
Linkage between the C1473G polymorphism in gene tph2 causing the replacement of Pro447 by Arg447 in TPH-2 molecule and enzyme activity in the mouse brain of 10 inbred strains was found.
      
The results indicate that the C1473G polymorphism in gene tph2 is the main factor determining the genetically defined variability of enzyme activity in the mouse brain.
      
We are the first to show that heat stress induces activity of ecdysone 20-monooxygenase in Drosophila females and enzyme activity correlates with the level of 20-hydroxyecdysone.
