| Abstract: | Summary The nucleotide sequences of the chloroplast genes for the alpha, beta and epsilon subunits of wheat chloroplast ATP synthase
have been determined. Open reading frames of 1512 bp, 1494 bp and 411 bp are deduced to code for polypeptides of molecular
weights 55201, 53796 and 15200, identified as the alpha, beta and epsilon subunits respectively by homology with the subunits
from other sources and by amino acid sequencing of the epsilon subunit. The genes for the beta and epsilon subunits overlap
by 4 bp. The gene for methionine tRNA is located 118 bp downstream from the epsilon subunit gene. Comparisons of the deduced
amino acid sequences of the alpha and beta subunits with those from other species suggest regions of the proteins involved
in adenine nucleotide binding. |
