  • Title: The animal and human plasma membrane (Ca(2+)+Mg2+)-ATPases--approaches to molecular arrangements of functional parts and oxidative changes.
    Author: Földes-Papp Z.
    Journal: Gen Physiol Biophys; 1992 Feb; 11(1):3-38. PubMed ID: 1323503.
    Abstract:
    The molecular structures of animal and human plasma membrane (Ca(2+)+Mg2+)-ATPases are not completely understood in part due to the fact that no suitable single crystal is available. The elucidation of the two-dimensional structure is in progress. The amino acid sequences of human erythrocyte and rat plasma membrane Ca2+ pump isoforms as well as of the pig smooth muscle plasma membrane Ca2+ pump are already known. This article reviews the present state of the knowledge in (Ca(2+)+Mg2+)-ATPase research of animal and human plasma membranes performed in the past few years, concerning in particular arrangements of proteolytically cleaved fragments, and relations between the erythrocyte (Ca(2+)+Mg2+)-ATPase in situ and the purified red cell enzyme, oxidative changes. Results of different experimental approaches concerning the structure of (Ca(2+)+Mg2+)-ATPases rather than the applications of the methods used are emphasized.
