Journal ArticleDOI
Spectroscopic properties of desulfoferrodoxin from Desulfovibrio desulfuricans (ATCC 27774)
Pedro Tavares,Natarajan Ravi,José J. G. Moura,Jean LeGall,Yun Hua Huang,Brian R. Crouse,Michael K. Johnson,Boi Hanh Huynh,Isabel Moura +8 more
TL;DR: Optical, electron paramagnetic resonance, and Mössbauer data of the gray desulfoferrodoxin indicate that both iron centers are in the high-spin ferric states, and resonance Raman studies confirm the structural similarity of center I and the distorted tetrahedral FeS4 center in desulforedoxin.
Journal ArticleDOI
Electron transfer between hydrogenases and mono- and multiheme cytochromes in Desulfovibrio ssp
TL;DR: A comparative study of electron transfer between the 16 heme high molecular mass cytochrome from Desulfovibrio vulgaris Hildenborough and the [Fe] and [NiFe] hydrogenases from the same organism indicates that the reduction of Hmc by the [ Fe] or [Ni Fe] hydrogenase is most likely mediated by cy tochrome c3.
Journal ArticleDOI
Direct spectroscopic evidence for the presence of a 6Fe cluster in an iron-sulfur protein isolated from Desulfovibrio desulfuricans (ATCC 27774)
Isabel Moura,Pedro Tavares,José J. G. Moura,Natarajan Ravi,Boi Hahn Huynh,M. Y. Liu,Jean LeGall +6 more
TL;DR: A novel iron-sulfur protein was purified from the extract of Desulfovibrio desulfuricans to homogeneity as judged by polyacrylamide gel electrophoresis, providing direct spectroscopic evidence for the presence of a 6Fe cluster in this newly purified protein.
Journal ArticleDOI
Hexaheme nitrite reductase from Desulfovibrio desulfuricans. Mössbauer and EPR characterization of the heme groups.
Cristina Costa,José J. G. Moura,Isabel Moura,M. Y. Liu,H. D. Peck,Jean LeGall,Yaning Wang,Boi Hanh Huynh +7 more
TL;DR: Mössbauer and EPR spectroscopy were used to characterize the heme prosthetic groups of the nitrite reductase isolated from Desulfovibrio desulfuricans (ATCC 27774), which is a membrane-bound multiheme cytochrome capable of catalyzing the 6-electron reduction of nitrite to ammonia.
Journal ArticleDOI
Nine-haem cytochrome c from Desulfovibrio desulfuricans ATCC 27774:primary sequence determination, crystallographic refinement at 1.8 and modelling studies of its interaction with the tetrahaem cytochrome c3.
Pedro M. Matias,Lígia M. Saraiva,Cláudio M. Soares,Ana Varela Coelho,Jean LeGall,Maria Arménia Carrondo +5 more
TL;DR: A role for 9Hcc as part of the assembly of redox proteins involved in recycling the molecular hydrogen released by the cell as a result of substrate oxidation is suggested.
