Bilirubin and biliverdin binding to rat Y protein (ligandin).

The binding of bilirubin to poly(L-lysine) produces an optically active complex at pH 10.1. Circular dichroism spectra of these complexes are distinguishable from those generated by binding of bilirubin to the high affinity sites on albumin. Comparison of the circular dichroism spectra of bilirubin bound to the hepatic protein ligandin with those of… CONTINUE READING
