These include Psb27, a small lipoprotein attached to the lumenal side of PSII, which has been assigned a role in regulating the assembly of the Mn(4)Ca cluster catalysing water oxidation. To gain a better understanding of Psb27, we have determined in this study the crystal structure of the soluble domain of Psb27 from Thermosynechococcus elongatus to a resolution of 1.6 . The structure is a four-helix bundle, similar to the recently published solution structures of Psb27 from Synechocystis PCC 6803 obtained by nuclear magnetic resonance (NMR) spectroscopy. Importantly, the crystal structure presented here helps us resolve the differences between the NMR-derived structural models. Potential binding sites for Psb27 within PSII are discussed in light of recent biochemical data in the literature Pracoviště Mikrobiologický ústav Kontakt Eliška Spurná, eliska.spurna@biomed.cas.cz, Tel.: 241 062 231 Rok sběru 2013
