Description

Reconstituted zinc-myoglobin (ZnMb) has been newly prepared by incorporating chemically-modified zinc-porphyrin cofactor appending an ethylenediaminetetraacetic acid (EDTA) moiety into apo-Mb. The divalent metal cation (Co2+, Cu2+, Ni2+, Mn2+, Zn2+, Mg2+) affinities of the EDTA moiety were determined by conducting UV-vis (and fluorescence) titration experiments in water. The photoinduced electron-transfer and energy-transfer reaction dynamics of the metal-bound ZnMb[M(edta)] were studied by fs-laser induced fluorescent lifetime measurements. (author)
