Abstract excerpt

The D2 protein of Photosystem II has five transmembrane helices (A-E). An extended loop, connecting helices D and E, contributes to the binding environments of the primary quinone electron acceptor QA, and that of the bicarbonate bound to the non-heme iron between QA and the secondary quinone electron acceptor QB. The residues from Ala240 to Thr243 are within a conserved sequence (240AEETYSMVTAN250) that...
