The atp operon: Nucleotide sequence of the genes for the γ, β, and ε subunits of Escherichia coli ATP synthase

Abstract

The nucleotide sequence of the promoter distal region of the atp (or unc) operon of Escherichia coli has been determined. It encodes the γ, β and e{open} subunits of the ATP-synthase complex and includes a noncoding sequence in which transcription of the operon probably terminates. This work completes the nucleotide sequence of the operon which contains nine genes: eight encode structural proteins of the ATP-synthase complex; a ninth, the first in the operon, may be a pilot for assembly. The genes for the α and β subunits have evolved from a common ancestor. © 1981 IRL Press Limited.
