Specific loss of the extrinsic 18 KDa protein from Photosystem II upon heating to 47 °C causes inactivation of oxygen evolution likely due to Ca release from the Mn-complex

Abstract

Exposure of Photosystem II (PS II) membrane particles from spinach to a temperature of 47 °C caused the rapid release of the 18 kDa protein in parallel to inactivation of oxygen evolution. Previously, it has been suggested that the first heat-jump response involves rapid Ca release from the Mn complex of O2-evolution, followed by the slower release of (2… (More)
