On multiple forms of bovine seminal plasma inhibin.
Out of a possible minimum of four, three distinct molecular species of bovine seminal plasma inhibin-differing either in Mr or in pI--have been purified to homogeneity. All three molecules exhibit the same proportion of alpha-helicity and beta-form when examined for their CD-spectra in a non-aqueous solvent medium. The implication of this finding for an induced conformation at the receptor-binding site for these hormonal peptides is briefly discussed.
