ABSTRACT

A comparative study of 27 enzymes and proteins in blue and silver foxes was carried out by means of starch gel electrophoresis. The structure of these enzymes and proteins is determined by about 33 genes. It is shown that a number of blood enzymes and proteins of these species is represented by a single electrophoretic form, while lactate dehydrogenase, carboanhydrase, arylesterase, carboxylesterase, diaphorase, hexokinase and tetrasolium oxidase have several forms. It is also found that these species differ in seven enzymes and proteins diaphorase, G-6-PD, adenylate kinase, carboxylesterase, albumin, prealbumin, transferrins. Other enzymes and proteins are similar in their electrophoretic mobility. The data obtained afford the evidence that the two species (Vulpes vulpes and Alopex lagopus) differ in a set of enzymes and proteins.
