Lanthanide porphyrin probes of heme proteins. Insertion of ytterbium(III)mesoporphyrin IX into apomyoglobin

Add time:07/18/2019    Source:sciencedirect.com

Apomyoglobin has been reconstituted with the lanthanide porphyrin complex, ytterbium(III)mesoporphyrin IX. The reconstituted material exhibits absorption and magnetic circular dichroic spectra significantly different from those of the ytterbium porphyrin itself. The sizeable, positive extrinsic Cotton effect in the Soret band of Yb-mesoporphyrin IX induced by the interactions with the globin indicates that the lanthanide porphyrin complex occupies the heme crevice.
