Summary
On the basis of the amino acid composition of the chromophore peptides, it can be assumed that Asp, Ser and 1/2 Cys are located near the biliverdin chromophore. Experiments for splitting of the chromophore lead us to expect a thioether bond in the linkages between biliverdin and apoprotein.
