Abstract

Recombinant holo Thermus thermophilus [7Fe-8S] ferredoxin was synthesized by cloning from Thermus thermophilus HB8 gene. A specific sequence (Pro-His-Val-Ile) at the N-terminus of the recombinant ferredoxin was determined by a rapid and highly sensitive mass spectral method using a novel Ru(II) Edman reagent, [(tpy)Ru(tpy-C6H4-NCS)](PF6)2 (tpy=terpyridine). The formation of the recombinant holoTtFd was established by the characteristic absorptions and CD extrema as [7Fe-8S] ferredoxin. The catalytic electron-transfer reactivity of the [7Fe-8S] ferredoxin between ferredoxin-NADP+ reductase and cytochrome c was recognized.
