The Mechanism of Photoinhibition of Spinach Thylakoids

There is conflicting evidence as to wether D1-protein is the primary target of photoinhibition [1] or P680, the reaction centre of photo-system II [2]. The present paper desribes photoinhibition within a two step process consisting of an oxygen radical induced inactivation at the QB-site followed by damage to reaction centre II through the degradation of the D1-protein.
