We report a new approach for the synthesis of multifunctional Au core@Prussian Blue analogous (PBA) shell nanoheterostructures that involves PBA shell growth on the surface of cyanide-stabilized gold nanoparticles. It permits the assembly of Au@KNi

Hexacyanochromate ion, (Cr(CN)6)3-, was applied to ribonuclease T1 (RNase T1), which specifically cleaves RNA chains at guanylic acid residues. From kinetic studies, this anion was shown to bind to the active site of RNase T1 as a competitive inhibitor. Therefore

Studies of redox reactions between the blue copper protein azurin and inorganic reagents have suggested the formation of discrete complexes between the reaction partners prior to the actual electron-transfer step. To get an insight into the structural nature of the

The small inorganic complex Cr(CN)6(3-) is a clean inhibitor of the ferredoxin: NADP+ reductase-catalysed oxidation of reduced spinach ferredoxin by NADP+. Independent spectrophotometric measurements show that millimolar additions of Cr(CN)6(3-) to mixtures of ferredoxin and ferredoxin NADP+ reductase give a

The 270-MHz proton NMR spectra of erabutoxins a, b and c from Laticauda semifasciata in 2H2O solution were observed together with [15-N6-acetyllysine]erabutoxin b, [27-N6-acetyllysine]-erabutoxin b and [47-N6-acetyllysine]erabutoxin b. The lysine epsilon-methylene proton resonances of erabutoxin b are assigned to individual
