title: [Studies on the activity, properties and isoenzymes of acid phosphatase in the erythrocytes of swine, horse, dog, cat, duck and chicken].
abstract: Acid phosphatase of erythrocytes of several species was investigated, with three isozymes having been recorded from swine (three types), three (two types) from horse, four (one type) from dog, two (two types) from cat, two (three types) from duck, and two (one type) from fowl. The Michaelis constant of the enzyme varied between 3.5 and 5 X 10(-4) M for the species involved. The species, however, differed slightly for the optimum pH of the enzyme. The average enzymatic activities were (5.68 +/- 0.42 for dog, 4.46 +/- 1.0 for horse, 3.8 +/- 0.24 for swine, 3.72 for cat, 2.5 +/- 0.62 for duck, and 1.9 +/- 0.8 for fowl. All values are units per gram haemoglobin. Even relatively low concentrations (0.2 or 1 mM) of copper, mercury, and cadmium ions were found to be strong inhibitors of the acid erythrocyte phosphatase.
