Abstract“Heteroenzyme” is the term applied to proteins of different origin that differ in their physical, chemical, and biochemical properties, but have the same biological action. Enzymes that have the same origin, and consist of very similar, but distinguishable proteins have been named “isozymes” [*]; they may also be designated as “multiple forms.”

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.

IT has previously been observed that crystalline salivary amylase gives two peaks in free electrophoresis1. The work recorded here shows that a sample of salivary amylase crystallized three times, which gave a single peak in the ultracentrifuge (Fig. 1), could be separated into four bands by disk electrophoresis on polyacrylamide gel2 (Fig. 2).

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 ...

Hypothyroidism and Isozyme Elevations
Archives of Internal Medicine, 1984To the Editor. —In the JanuaryArchives, Klein and Levey 1 discussed unusual manifestations of hypothyroidism. In their discussion of musculoskeletal features, elevations of the levels of creatine kinase (CK) and lactate dehydrogenase (LDH) were mentioned as being observed in up to 80% of the patients with hypothyroidism.

Bovine pyruvate kinase isozymes and hybrid isozymes
Archives of Biochemistry and Biophysics, 1976Abstract Electrophoresis of various bovine tissue extracts revealed, in addition to the three major homotetrameric isozymes of pyruvate kinase (K 4 , L 4 , and M 4 ), numerous intermediate bands that behave electrophoretically as hybrid isozymes. Kidney, for example, contains both K-L and K-M hybrid sets.

Abstract Isozymes have been compared in leaves grown under controlled conditions for 31 species in the 12 seagrass genera. In isozyme patterns the three genera Zostera, Phyllospadix an and Heterozostera , of subfamily Zosteroideae of Potamogetonaceae, showe greater overall similarity to each other than to members of subfamilies Posidonioideae and ...

Enolase isozymes from Ricinus communis: Partial purification and characterization of the isozymes
Archives of Biochemistry and Biophysics, 1984The plastid and cytosolic isozymes of enolase from developing endosperm of castor oil seeds, Ricinus communis L. cv. Baker 296, were separated and partially purified. Each purified isozyme had a specific activity of approximately 200 mumol min-1 mg protein.

AMP deaminase (AMP aminohydrolase EC, 3.5.4.6) catalyzes deamination of AMP to form IMP and ammonia. Although the physiological role of this enzyme remains obscure, it may be important to stabilize the adenylate charge (1), in the conversion of adenine nucleotide to inosine or guanine nucleotide (2–5) and furthermore as a key enzyme in the purine ...

Electrophoretic technique combined with enzyme-specific stains has provided the most precise way of estimating genetic variability in many plant taxa. Within the genus Lycopersicon this method has been successfully applied by Rick and his colleagues for measuring the extent of variation both in cultivated forms and wild species (Rick 1976a, 1983 ...
