RESUMO
The genes encoding the beta (atpB) and epsilon (atpE) subunits of the ATPase from the cyanobacterium Anabaena sp. strain PCC 7120 were cloned, and their sequences were determined. atpB and atpE are each single-copy genes in the Anabaena genome. The two genes are separated by a 96-base-pair intergenic spacer and transcribed as a single mRNA of 2.3 kilobases that initiates approximately 200 base pairs upstream of the atpB coding region. The predicted translation product of atpB has 81 and 68% amino acid identity with the corresponding proteins from spinach chloroplasts and Escherichia coli, respectively. The atpE gene product is less conserved, with 41 and 33% amino acid identity with the corresponding proteins from spinach chloroplasts and E. coli, respectively. The organization of the Anabaena atpB and atpE genes relative to adjacent genes differs from that of both E. coli and chloroplasts.
