Light-induced D1-protein degradation in isolated photosystem II core complexes.
Photoinhibitory illumination of isolated oxygen evolving photosystem II core complexes results in a substantial degradation of the D1-protein which is accompanied by the appearance of high amounts of at least 4 different degradation products. It is suggested that the degradation is due to a protease that is an integral part of the photosystem II complex.
