[Effect of protein and protein-free nutrition on the adaptability of transamination reactions in the liver].
It has been shown in experiments on rats that aspartate aminotransferase (AsAT) and alanine aminotransferase (A1AT) playing an important role in amino acid metabolism by the liver are easily adaptable to nutrition conditions. The activity of the enzymes increase in the liver of rats kept on diet containing 24% of casein and on complete fasting but decreases in the course of administering isocaloric protein-free diet. Replacement of protein-free diet by protein diet after 10 days leads to a drastic increase in the AsAT and A1AT activity.
