Abstract
THIS is a preliminary report on a ‘polybase effect’ consisting of a considerable change in the spectrum of hæmin on its interaction with polylysine in alkaline solution. Two different types of complex are formed with poly-L-lysine which may be associated with the folded and unfolded structure of the peptide. These simple hæmin–polypeptide complexes are considered to serve as models for iron–porphyrin-containing enzymes, and it is hoped that they will add to our knowledge of the prosthetic group-protein interaction and of the catalytic properties connected with it.
