In this paper we continue the study of a number of properties of protomitochondria--small young mitochondrial organelles in the animal cells. Protomitochondria were obtained by filtration of total suspension of mitochondria of rat liver through Millipore filters. Protomitochondria contain an active respiratory chain as evidenced by the high rate of oxygen consumption during succinate and NADH oxidation. A shunt succinate:tetrazolium-reductase activity of protomitochondria was lower and NADH-tetrazolium-reductase activity was higher than that in mitochondria. Electrophoresis and gel filtration found no qualitative differences between protomitochondria, 0.25-0.45 μm in diameter, and mitochondria in major protein composition, but some quantitative differences in several bands were found. Perhaps, these differences reflect the process of intracellular maturation of protomitochondria to mitochondria. The data obtained are important for understanding the mitochondriogenesis in the animal cells.
