Genes for ATP synthase polypeptides

The genes for three subunits of CFg are clustered near the gene for the a subunit in chloroplast DNA. The gene (atpH) for CFg subunit III was originally located approximately 2 kbp upstream from aipA in wheat chloroplast DNA [149,159] and has subsequently been located in a similar position in other higher plants [156,160,161]. Nucleotide sequence determination indicates that the primary 

The genes for the y and 8 subunits of CFj and for CFq subunit II are most likely located in nuclear DNA, but they have not yet been isolated. Each of these polypeptides has been shown to be synthesized as a larger precursor form on translation of poly(A) RNA in vitro [142,146]. The isolation and characterization of the nuclear genes for these three subunits of ATP synthase is urgently required.
