It is a heterodimer, with a 14 kD light chain and 34 kD heavy chain, activated from Procathepsin D autocatalytically and with assistance from cysteine proteases. Between the two lobes is an extended active site that accomidates 8 residues. CD specificity is gained by active site preference for hydrophobic residues. At the base of the active site are the two aspartate residues involved in catalysis of peptide bonds. | It is a heterodimer, with a 14 kD light chain and 34 kD heavy chain, activated from Procathepsin D autocatalytically and with assistance from cysteine proteases.
