newly synthesized precursors of the vacuolar protease carboxypeptidase y ( cpy ) were converted to mature cpy with similar kinetics in mutant and wild-type cells . chcl cells did not aberrantly secrete cpy and immunolocalization techniques revealed most of the cpy in chcl cells within morphologically identifiable vacuolar structures .
