Abstract

The biologically and nanotechnologically important heme protein cytochrome b562 was reconstructed with zinc and copper porphyrins, leading to significant changes in the spectral, redox and electron transfer properties. The Cu form shifts the redox potential by +300 mV and exhibits high electron transfer, while the Zn form is redox inert.
