| + | PsbP is a membrane-extrinsic subunit of the water-oxidizing complex photosystem II (PS II). The evolutionary origin of PsbP has long been a mystery because it specifically exists in higher plants and green algae but not in cyanobacteria. We report here the crystal structure of PsbP from Nicotiana tabacum at a resolution of 1.6 A. Its structure is mainly composed of beta-sheet, and is not similar to any structures in cyanobacterial PS II. However, the electrostatic surface potential of PsbP is similar to that of cyanobacterial PsbV (cyt c(550)), which has a function similar to PsbP. A structural homology search with the DALI algorithm indicated that the folding of PsbP is very similar to that of Mog1p, a regulatory protein for the nuclear transport of Ran GTPase. The structure of PsbP provides insight into its novel function in GTP-regulated metabolism in PS II. | ||
