Description
1. 1. The properties of the membrane-bound calcium-pumping protein, the (Ca2+ + Mg2+)-ATPase (ATP phosphohydrolase, EC 3.6.1.3) were compared in erythrocyte ghosts isolated from five mammalian species-human (Homo sapiens), bovine (Bos taurus), porcine (Sus scrofa malitensis), ovine (Ovis aries crassicandus) and caprine (Capra hircus syriaca). 2. 2. The specific activity of the enzyme in porcine erythrocytes is one order of magnitude higher than in the other species. It was also stimulated to various extents by the regulator protein, calmodulin, and by phosphatidylinositol in all the species. 3. 3. Analysis of membrane proteins revealed a number of differences which seem to suggest that the molecular architecture of the red cell membrane influences the activity of the enzyme. © 1985.
