ATP synthase is a large multimeric protein complex responsible for generating the energy molecule adenosine triphosphate (ATP) in most organisms. The catalysis involves the rotation of a ring of c-subunits, which is driven by the transmembrane electrochemical gradient. This dissertation reports how the eukaryotic c-subunit from spinach chloroplast ATP synthase has successfully been expressed in Escherichia coli and purified in mg quantities by incorporating a unique combination of methods. Expression was accomplished using a codon optimized gene for the c-subunit, and it was expressed as an attachment to the larger, more soluble, native maltose binding protein (MBP-c1). The fusion protein …
