| + | Plastocyanin is an electron-transfer protein which has been largely used for biophysical studies as well as for protein-engineering experiments. A surface disulfide bridge has been engineered in poplar plastocyanin to allow protein chemisorption on gold substrates. The mutated plastocyanin crystal structure has been studied at 1.6 A resolution (R factor = 0.145, R(free) = 0.205) to characterize the effects of the engineered disulfide on the overall protein structure and on the Cu-coordination sphere in view of biophysical applications. The new orthorhombic crystal form isolated for the mutated plastocyanin displays two protein molecules per asymmetric unit. | ||
