[Ability of blood protein, typical of normal growth, to activate glycolysis and inhibit the Pasteur reaction].

Formation of lactic acid by the extracts from the healthy rabbit muscles was studied as affected by the sera of embryos, newborn rabbits and pregnant female rabbits. The blood sera and beta-globulin isolated from them are established to activate anaerobic glycolysis and inhibit the Pasteur reaction. It is shown that protein typical of normal growth, belonging to beta-globulins and circulating in blood of the embryos, newborn rabbits from the first to the fifteenth day of development is "responsible" for this phenomena. Correlation is found between the precipitation test for detecting this protein and its biological effect on glycolysis and the Pasteur reaction.
