[Comparative characteristics of the activity of enzyme systems for nitrogen metabolism in the liver of human fetuses during embryogenesis].
The activities of alanine aminotransferase (ES 2.6.1.2), aspartate aminotransferase (EC 2.6.1.1) and monoaminoxidase (EC 1.4.3.4) in the liver nuclei and mitochondria of human fes rises gradually beginning from the early periods of the antenatal development till birth and reaches the highest value in the last month of the fetus intra-uterine life. The monoaminoxidase activity is found in the liver nuclei of 21-32-week human feti. The activity of RNase (EC 2.7.7.16) and DNase (EC 3.1.4.5) in the liver nuclei is 10 and 15 times as low, respectively, by the 40th week of development, and 1.5 times as low in mitochondria.
