obsolete chloroplast proton-transporting ATP synthase complex, catalytic core CF(1) https://github.com/geneontology/go-ontology/issues/27253 true OBSOLETE. The catalytic sector of the mitochondrial hydrogen-transporting ATP synthase; it comprises the catalytic core and central stalk, and is peripherally associated with the chloroplast thylakoid membrane when the entire ATP synthase is assembled. The chloroplast F0 domain contains three alpha, three beta, one gamma, one delta, and one epsilon subunits. cellular_component GO:0033174 The reason for obsoletion is that this term unnecssarily specified a cellular compartment. chloroplast proton-transporting F-type ATPase complex, catalytic core CF(1) proton-transporting ATP synthase complex
