The primary structure of the γ-subunit of the ATPase from Synechocystis 6803

AbstractThe nucleotide sequence of the gene coding for the FoF1-ATPase γ-subunit (atpC) from the transformable cyanobacterium Synechocystis 6083 has been determined. The deduced translation product consists of 314 amino acid residues and is highly homologous (72% identical residues) to the sequences of other cyanobacterial γ-subunits. The Synechocystis 6803 sequence is also homologous to the chloroplast γ-sequence. Like in the other cyanobacterial subunits, only the first of the 3 cysteine residues, which are involved in energy-linked functions of the γ-subunit in spinach chloroplasts, is conserved in Synechocystis 6803
