An NMR structural study of nickel-substituted rubredoxin
Goodfellow, Brian J.; Duarte, Iven C. N.; Macedo, Anjos L.; Volkman, Brian F.; Nunes, Sofia G.; Moura, Isabel; Markley, John L.; Moura, José J. G.J Biol Inorg Chem (2010) 15:409–420 DOI 10.1007/s00775-009-0613-6 ; The Ni(II) and Zn(II) derivatives of Desulfovibrio vulgaris rubredoxin (DvRd) have been studied by NMR spectroscopy to probe the structure at the metal centre. The βCH2 proton pairs from the cysteines that bind the Ni(II) atom have been identified using 1D nuclear Overhauser enhancement (NOE) difference spectra and sequence specifically assign...
Zinc-substituted desulfovibrio gigas desulforedoxins
Moura, Isabel; Goodfellow, Brian J.; Nunes, Sofia G.; Rusnak, Frank; Ascenso, Carla; Moura, José J. G.; Volkman, Brian F.; Markley, John L.Protein Science (2002), 11:2464–2470 ; Desulfovibrio gigas desulforedoxin (Dx) consists of two identical peptides, each containing one [Fe-4S]center per monomer. Variants with different iron and zinc metal compositions arise when desulforedoxin is produced recombinantly from Escherichia coli. The three forms of the protein, the two homodimers [Fe(III)/Fe(III)]Dx and [Zn(II)/Zn(II)]Dx, and the heterodimer [Fe(I...
