NMR solution structures of two mutants of desulforedoxin.

Journal of inorganic biochemistry - 1 Jan 2003

Goodfellow B J, Rusnak F, Moura I, Ascenso C S, Moura J J G

Abstract excerpt

The differences in geometry at the metal centres in the two known [Fe-4S] proteins rubredoxin (Rd) and desulforedoxin (Dx) are postulated to be a result of the different spacing of the C-terminal cysteine pair in the two proteins. In order to address this question, two mutants of Desulfovibrio gigas Dx with modified cysteinyl spacing were prepared and their solution structures have been determined by NMR. Mutant...
