Physical characterization of a totally synthetic 2[4Fe-4S] clostridial ferredoxin
Abstract
The 2[4Fe-4S] ferredoxins (Fd) serve as electron carriers in fermentative and photosynthetic pathways. In order to determine the influence of specific amino acids on the electron transferring properties of bacterial ferredoxins, Rabinowitz and co-workers have used semisynthetic procedures to substitute or delete specific amino acids near the N-terminus of native ferredoxins. In this paper we report the first totally synthetic 2[4Fe-4S] ferredoxin, which, along with future synthetic variants, will be used to determine the effects of specific amino acid residues throughout the protein upon both its equilibrium and dynamic properties. The apoprotein was synthesized via standard tBOC procedures on polyvinyl (PAM) resins based on principles outlined by Merrifield.
