[Regularities of organ-specific expression of enzyme systems in cattle]

The organ specificity of creatine kinase, esterase, isocitrate dehydrogenase lactate dehydrogenase, nucleoside phosphorylase, adenylate kinase, hexokinase, malate dehydrogenase, malic enzyme, glucose-6-phosphate dehydrogenase of black-white cattle has been studied. Esterases, creatine kinase, adenylate kinase, hexokinase and glucose-6-phosphate dehydrogenase have a very wide spectrum of the organ variabilities. Liver and heart have the largest specificity of enzymes activity. Some peculiarities of isozyme spectrum are found in ovaries and spleen.
