Implications of oxidovanadium(IV) binding to actin
Ramos, Susana; Almeida, Rui M.; Moura, José J. G.; Aureliano, M.Oxidovanadium(IV), a cationic species (VO2+) of vanadium(IV), binds to several proteins, including actin. Upon titration with oxidovanadium(IV), approximately 100% quenching of the intrinsic fluorescence of monomeric actin purified from rabbit skeletal muscle (G-actin) was observed, with a V50 of 131 μM, whereas for the polymerized form of actin (F-actin) 75% of quenching was obtained and a V50 value of 320 μM....
Gd(III) chelates as NMR probes of protein-protein interactions. Case study: rub...
Almeida, Rui M.; Geraldes, Carlos F. G. C.; Pauleta, Sofia R.; Moura, José J. G.Inorganic Chemistry 50(21):10600-7; Two cyclen-derived Gd probes, [Gd-DOTAM](3+) and [Gd-DOTP](5-) (DOTAM = 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetamide; DOTP = 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetrakis(methylenephosphonate)), were assessed as paramagnetic relaxation enhancement (PRE)-inducing probes for characterization of protein-protein interactions. Two proteins, Desulfovibrio gigas rubredo...
