S. Aono et al., PHOTOREDUCTION OF CYTOCHROME-C WITH ZINC PROTOPORPHYRIN RECONSTITUTEDMYOGLOBIN (ZNPP-MB), Journal of molecular catalysis. A, Chemical, 95(2), 1995, pp. 193-196
Photoreduction of cytchrome c (cyt, c) proceeded by irradiation of the
visible light in the reaction system consisting of EDTA, ZnPP-Mb and
cyt. c. About 90% of cyt. c was reduced in 20 min of irradiation of th
e light. Photoinduced electron transfer occurs between ZnPP-Mb and cyt
. c in the above system. Laser flash photolysis showed that the oxidat
ive quenching of (ZnPP)-Zn-3-Mb by the oxidized cyt. c took place and
the quenching rate constant was 8.5 X 10(5) M(-1)s(-1).
