Coboglobins: oxygen-carrying cobalt-reconstituted hemoglobin and myoglobin.

Abstract

In this work we show that it is possible to prepare and study a cobalt-substituted hemoglobin-a coboglobin (Cb).-and that this reconstituted metalloprotein exhibits reversible oxygen binding. The effect of the protein environment on Co(II)-protoporphyrin IX is directly observed by esr measurements on deoxy- and oxy-Cb and by oxygen uptake measurements, all… (More)
