In cyanobacteria and chloroplasts, in the presence of light, PSII functions as a water-plastoquinone oxidoreductase, transferring electrons from water to plastoquinone, whereas other photosynthetic bacteria carry out anoxygenic photosynthesis and oxidize other compounds to re-reduce the photoreaction center.","xrefs":[{"dbCode":"ISBN","dbId":"0943088399"},{"dbCode":"PMID","dbId":"9821949"}]},"children":[{"id":"GO:0009539","relation":"part_of"},{"id":"GO:0030096","relation":"is_a"},{"id":"GO:0030095","relation":"is_a"},{"id":"GO:0009654","relation":"part_of"},{"id":"GO:0009783","relation":"part_of"}],"aspect":"cellular_component","usage":"Unrestricted"}],"pageInfo":null}
