title: Cleavage specificity of boar acrosin on polypeptide substrates, ribonuclease and insulin B-chain.
abstract: The cleavage specificity of boar acrosin is, like that of trypsin, strictly limited to the arginyl and lysyl bonds, as demonstrated for the oxidized B-chain of insulin. In addition, in this polypeptide substrate as well as in reduced and carboxymethylated ribonuclease, these peptide bonds are hydrolyzed by acrosin and trypsin with nearly identical velocities.
