It was still necessary to demonstrate that the process requires energy, and indeed, following our initial characterization of degradation of abnormal hemoglobin in the intact cell, we showed that the process required energy (was published in 1978 in the proceedings of a proteolysis meeting held in Buffalo, NY), and felt that the time was ripe to break the cell open and isolate and characterize the non-lysosomal and ATP-dependent proteolytic enzyme (s).
