Journal ArticleDOI
Widely Differing Photochemical Behavior in Related Octahedral {Ru-NO}6 Compounds: Intramolecular Redox Isomerism of the Excited State Controlling the Photodelivery of NO
TL;DR: DFT computations provide an electronic structure picture of the photoactive excited states that helps to understand this apparently abnormal behavior of the transtrans-[(NC)Ru(py)(4)(mu-CN](3+) (py = pyridine) in aqueous solution.
Journal ArticleDOI
A new ruthenium nitrosyl species based on a pendant-arm 1,4,8,11-tetraazacyclotetradecane (cyclam) derivative: An experimental and theoretical study
TL;DR: In this paper, the complex cis-[Ru(Lpy)NO]3+ (I) (Lpy = N-(2-methylpyridyl)1,4,8,11-tetraazacyclotetradecane) was prepared by the stoichiometric reaction between Ru(dmso)4Cl2 and Lpy and an excess of NaNO2 in ethanolic medium, followed by acidification of the solution.
Journal ArticleDOI
All-trans-[ClRu(II)(py)4(NC)Ru(II)(py)4(CN)Ru(II)(py)4(NO)](PF6)4: a redox-active 2-donor/1-acceptor system based on the electrophilic {RuNO}6 motif.
TL;DR: The spectroscopic and spectroelectrochemical information reveals that the one-electron reduction is centered on the nitrosyl moiety to yield a {RuNO}(7) species, while oxidation occurs on the chlororuthenium side of the molecule.
Journal ArticleDOI
Probing the chemotaxis periplasmic sensor domains from Geobacter sulfurreducens by combined resonance Raman and molecular dynamic approaches: NO and CO sensing.
Teresa Catarino,Miguel Pessanha,Ariel G. De Candia,Zélia Gouveia,Ana P. Fernandes,P. Raj Pokkuluri,Daniel H. Murgida,Marcelo A. Marti,Smilja Todorovic,Carlos A. Salgueiro +9 more
TL;DR: Spectroscopic data and MD calculations revealed subtle differences in the binding properties and structural features of formed CO and NO adducts, but also indicated a possibility that a (5c) high-spin/(6c) low-spin redox-linked equilibrium could drive the physiological sensing of Gs cells.
Journal ArticleDOI
Electron transfer dynamics of Rhodothermus marinus caa3 cytochrome c domains on biomimetic films
Maria F. Molinas,Ariel G. De Candia,Sergio H. Szajnman,Juan B. Rodriguez,Marcelo A. Martí,Manuela M. Pereira,Miguel Teixeira,Smilja Todorovic,Daniel H. Murgida +8 more
TL;DR: The results indicate that the transient interaction between Cyt-D and HiPIP relies upon a delicate balance of hydrophobic and polar contacts for establishing an optimized electron transfer pathway that involves the exposed edge of the heme group and guaranties efficient inter-protein electron transfer on the nanosecond time scale.
