Abstract
Treatment of oxygen‐evolving photosystem II particles isolated from the thermophilic cyanobacterium, Synechococcus sp. with β‐octylglucoside specifically solubilized two intrinsic polypeptides of 31 and 28 kDa from the particles. The removal of the two polypeptides had no significant effect on photoreduction of the bound quinone acceptor QA. The results indicate that the 31 and 28 kDa polypeptides are not essential for the primary charge separation and subsequent reduction of QA and hence support the view that the reaction center and QA are located on the chlorophyll‐carrying 47 kDa subunit.Keywords
