[Effect of pH and substitution of H2O for D2O on oxygen liberation by chloroplasts]. / Vliianie pH i zameshcheniia H2O na D2O na vydelenie kisloroda khloroplastami.

The rate of dark relaxation of the oxygen evolving system in chloroplasts is shown to depend on the value of the surface charge of some chloroplast membrane component having protein nature and isoelectric point at pH 6.0. The substitution of H2O for D2O leads to isoelectric point shift of this protein.
