光系统II（PS II）的活性受到多种环境因素的严重限制，并且在环境胁迫下，由PS II的损伤速率和受损PS II的修复速率之间的平衡决定。氧化应激对损伤和修复的影响可以分别研究，并且似乎，虽然光可以直接损伤PS II，但氧化应激主要通过抑制PS II的修复来起作用。对蓝细菌的研究表明，氧化应激抑制了蛋白质的重新合成，特别是D1蛋白，这是PS II修复所必需的。
The activity of Photosystem II (PS II) is severely restricted by a variety of environmental factors and, under environmental stress, is determined by the balance between the rate of damage to PS II and the rate of the repair of damaged PS II. The effects of oxidative stress on damage and repair can be examined separately, and it appears that, while light can damage PS II directly, oxidative stress acts primarily by inhibiting the repair of PS II. Studies in cyanobacteria have demonstrated that oxidative stress suppresses thede novosynthesis of proteins, in particular, the D1 protein, which is required for the repair of PS II.
