Copper -imidazole interactions

At pH 7.8, the structure of reduced (Cu1) pfastocyanin has a structure very similar to that of Cu" ptastocyann (Fig. 19.15) except for small differences in bond lengths. At pH 3.8, the copper is IrigonaOy coordinated wah the fourth interaction (Cu-imidazole) broken. Predict and discuss the redox activity of plastocyanin as a Fixiction of pH. [Pg.494]

One Cu (CuA) is held by three imidazole groups and is thought to be the site of interaction with ascorbate. The other copper, CuB, which is 1.1 nm away from CuA, is held by two imidazoles. The substrate binds adjacent to Cu,.463... [Pg.1064]

The complexation reactions of pilocarpine with cobalt(II), nickel(II), copper(II), and zinc(II) ions were investigated (84). The complexes were characterized by spectrophotometry, conductivity, ESR, NMR, and magnetic susceptibility measurements. In each case, the metal ion was pseudo-tetrahedrally coordinated. Pilocarpine interacts with the metal ion through the imidazole ring. [Pg.291]
