Abstract

PsbO, PsbP and PsbQ are the extrinsic proteins associated with the oxygen-evolving (OE) engine of all known higher plants. However their presence is not constant throughout all known oxy-photosynthetic organisms. For this reason, comparative analyses of the sequence and the structure of these proteins in different species from prokaryotes to eukaryotes may allow unravelling of the evolutionary track that they have followed and infer new hints about their function in the OE complex. The results show that PsbP and PsbQ present different evolutionary profiles, and that PsbQ is more closely associated to PsbO and probably to the manganese stabilizing role assigned to this protein.
