Science, 1966
A new method of starch-gel electrophoresis using a technique of staining dependent on enzyme activity has been employed to demonstrate the isozymes of aldolase from a variety of human, rat, and frog tissues. Five of these isozymes were detected in man, seven in the rat, and at least four in the frog. The abilities of these isozymes to cleave fructose-1,

BioScience, 1975
Isozymes are now a common part of the scientific vocabulary, but their recognition is relatively recent, having been first announced in 1959 (Markert and Mqller). Prior to that time, molecular heterogeneity had often been noted in enzyme preparations, but such heterogeneity was usually attributed to contaminants or to partially denatured or degraded ...

Human placental aminopeptidase isozymes
Experientia, 1974Charakterisierung zweier Arten von Aminopeptidase (AP)-Isozymen in den Lysosomen und Mikrosomen der menschlichen Plazenta. Die im Serum schwangerer Frauen auftretende AP hatte ahnliche Eigenschaften wie die Lysosomen-AP. Die Erhohung der Aminopeptidase beruhte folglich auf dem Austritt lysosomaler Enzyme aus der Plazenta.

Publisher Summary This chapter focuses on the concept of isozymes. In 1964, a subcommittee of the International Union of Biochemistry recommended that multiple enzyme forms in a single species, catalyzing essentially the same reaction but differing in various ways should be called “isozymes,” or “isoenzymes.” Nevertheless this definition was too ...

Isozymes of Phenylalanine Hydroxylase
Science, 1972Three isozymes of phenylalanine hydroxylase exist in adult rat liver. They are chromatographically unique. Partial characterization suggests that they are similar in chemical properties and differ only in charge. Estimation of the Stokes radii indicates that the isozymes have similar molecular weights of about 200,000. Two isozymes exist in human fetal

Animal carbonic anhydrase isozymes
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1971Abstract 1. 1. The relative carbonic anhydrase activities of the erythrocytes of various animals based on humans as 100 was rabbits 119, dogs 78, goats 85, horses 33, cows 234 and guinea pigs 146. 2. 2. Only rabbit and horse erythrocytes had cathodically migrating carbonic anhydrases characteristic of the C isozyme in humans. 3. 3.

Arachidonate 12-Lipoxygenase Isozymes
1999A lipoxygenase is an enzyme which incorporates one molecule of oxygen into arachidonic acid or other polyunsaturated fatty acids producing hydroperoxy acids with a conjugated diene system. Enzymes oxygenating at the positions 5, 8, 12 and 15 of arachidonic acid and producing the corresponding hydroperoxy eicosatetraenoic acid (HpETE) have been isolated

Isozyme Specificity to Temperature
Nature New Biology, 1972TEMPERATURE treatment of styles leads to self-compatibility in otherwise self-incompatible species of Oenothera2,3, Lilium4 and Trifolium5,6. I have studied the temperature treatment of esterase in styles of several species and hybrids of Lilium by using gel electrophoresis.
