Importance of the N-terminal sequence of the extrinsic 23 kDa polypeptide in Photosystem II in ion retention in oxygen evolution.

Biochimica et biophysica acta - 9 Mar 2001

Ifuku K, Sato F

Abstract excerpt

The function of the extrinsic 23 kDa polypeptide (OEC23) in Photosystem II (PS II) is to retain Ca(2+) and Cl(-) during the S-state turnover of the Mn cluster in photosynthetic oxygen evolution. Recombinant OEC23s from several plant species were produced in Escherichia coli to characterize the molecular mechanism of the OEC23 function then used in reconstitution experiments. One tobacco isoform, OEC23 (2AF), had...
