[The effect of antibodies against Ca2(+)-ATPase and its hydrophobic fragment on the activity of this enzyme and on the passive transport of Ca2(+)].

It is shown that both Ca(2+)-ATPase and its hydrophobic fragment are immunogenic factors. A region between hydrophobic and hydrophilic parts of Ca(2+)-ATP-ase is immunogenic. These antibodies clearly inhibit inflow and outflow of Ca2+ through a hydrophobic fragment reconstructed into liposomes and do not influence Ca(2+)-ATPase activity.

[Effect of amino acids on transformation of glucose oxidase as antigen in tissues of immunized animals].

The effect of certain amino acids on transformation of glucoseoxidase as an antigen in different tissues of the animals immunized with it showed that the used glucoseoxidase of the fungus Penicillium vitale Pidopl. et Bilaj possesses antigenic properties peculiar to this enzyme isolated from other sources. 1.
