Coproporphyrins 87-101 hemopexin Oryctolagus cuniculus 7-16 1164515-3 1975 Results of competitive binding experiments suggest that all four porphyrins bind at the heme-binding site of hemopexin, and that the relative affinity of rabbit hemopexin for these porphyrins is: deuteroheme greater than coproporphyrin I or III greater than uroporphyrin I or III. Coproporphyrins 221-235 hemopexin Oryctolagus cuniculus 161-170 1164515-4 1975 These findings provide further evidence that hemopexin may function as a transport protein for circulating coproporphyrins as well as for heme.
