The oocyte at the end of oogenesis, mature egg and developing embryo of the loachMisgurnus fossilis L.) are characterized by indentical enzyme profiles of the Embden-Meyerhof chain, pentose phosphate cycle and key gluconeogenic enzymes. However, the carbohydrate metabolism in the oocyte differs substantially from that in the embryo. Oocyte maturation is(More)
An acceleration of the rate of glycogenolysis in the early embryogenesis of the loach (Misgurnus fossilis L.) is accompanied by an increase of the content of hexose monophosphates, the rate of lactate formation and the rate of respiration. The unfertilized egg and the intact embryo of the loach have an identical activity of phosphorylase (EC 2.4.1.1.) and a(More)
An acceleration of glycogenolysis after fertilization in loach (Misgurnus fossilis L.) eggs is not related to an increase of active phosphorylase (EC 2.4.1.1). The activity of “debranching” enzymes (amylo-1,6-glucosidase; dextrin-6-glucohydrolase, EC 3.2.1.33) considerably increases during early embryogenesis. These facts suggest that the enhancement of(More)
Lev S. Milman, a well known scientist, specialist in the field of developmental biology and biochemistry, passed away on March 3, 2004. Milman made a significant contribution to science, above to studies of biochemical problems of ontogenesis. His studies in the area of nucleic acids and some other areas of biochemistry are also well known. He is the author(More)
The decrease of the phosphorylated state of the adenine nucleotide system (ATP)/(ADP) (HPO 4 −2 ) during oocyte maturation of the loach (Misgurnus fossilis L.) correlated with the fall of the (NAD+)/(NADH) ratio. A increase of the cytoplasmic (NADP+)/(NADPH) ratio was also found. Beim Reifen der Oocyte vonMisgurnus fossilis L. wird eine wesentliche(More)
