3 GO annotations of cellular component

Name Definition
chloroplast thylakoid membrane The pigmented membrane of a chloroplast thylakoid. An example of this component is found in Arabidopsis thaliana.
extrinsic component of membrane The component of a membrane consisting of gene products and protein complexes that are loosely bound to one of its surfaces, but not integrated into the hydrophobic region.
photosystem II oxygen evolving complex A complex, composed of a cluster of manganese, calcium and chloride ions bound to extrinsic proteins, that catalyzes the splitting of water to O2 and 4 H+. In cyanobacteria there are five extrinsic proteins in OEC (PsbO, PsbP-like, PsbQ-like, PsbU and PsbV), while in plants there are only three (PsbO, PsbP and PsbQ).

2 GO annotations of biological process

Name Definition
photosynthesis The synthesis by organisms of organic chemical compounds, especially carbohydrates, from carbon dioxide (CO2) using energy obtained from light rather than from the oxidation of chemical compounds.
photosystem II stabilization The stabilization of the photosystem II protein complex, resulting from the phosphorylation of its structural protein subunits, in a cell actively involved in photosynthesis.
