Crystal Structure of PsbQ from Synechocystis sp. PCC 6803 at 1.8 A: Implications for Binding and Function in Cyanobacterial Photosystem II
Biochemistry, 49:2765-2767, 2010

PubMed Abstract: In Synechocystis sp. PCC 6803, PsbQ is associated with photosystem II (PSII) complexes with the highest activity and stability. However, this subunit is not found in PSII X-ray crystallographic structures from Thermosynechococcus elongatus or Thermosynechococcus vulcanus. We present the crystal structure of cyanobacterial PsbQ determined in the presence and absence of Zn(2+). The protein has a well-defined helical core, containing four helices arranged in an up-down-up-down fold. A conserved potential interaction site composed of a divalent metal binding site and adjacent hydrophobic pocket has been identified.
