The results show that while a larger polypeptide substrate carrying the HD1 / 3C site was processed more efficiently than a polypeptide substrate carrying the POL / Zn site , cleavage of the synthetic peptide substrates containing these two cleavage sites occurred at similar efficiencies .
 GENE: HD1 / 3C site; GENE: POL / Zn site
