Chain A (GFP_AEQVI | P42212)

molecular function
	GO:0003674	molecular_function	Elemental activities, such as catalysis or binding, describing the actions of a gene product at the molecular level. A given gene product may exhibit one or more molecular functions.
biological process
	GO:0008218	bioluminescence	The production of light by certain enzyme-catalyzed reactions in cells.
	GO:0006091	generation of precursor metabolites and energy	The chemical reactions and pathways resulting in the formation of precursor metabolites, substances from which energy is derived, and any process involved in the liberation of energy from these substances.
	GO:0018298	protein-chromophore linkage	The covalent or noncovalent attachment of a chromophore to a protein.
cellular component
	GO:0005575	cellular_component	The part of a cell, extracellular environment or virus in which a gene product is located. A gene product may be located in one or more parts of a cell and its location may be as specific as a particular macromolecular complex, that is, a stable, persistent association of macromolecules that function together.
