General Information

EC Number General Information Comment Organism
1.10.3.9 additional information identification of oxidized amino acid residues in the D1, D2 CP47, and CP43 proteins, in the vicinity of the Mn4O5Ca cluster active site of PS II, by mass spectrometry. The residues are modified by reactive oxygen species generated within the PS II complex Spinacia oleracea
1.10.3.9 physiological function photosystem II is a light-driven water-plastoquinone oxidoreductase. It produces molecular oxygen as an enzymatic product. Under a variety of stress conditions, reactive oxygen species are produced at or near the active site for oxygen evolution Spinacia oleracea
