Abstract:
:ATP-dependent release of TCA-precipitable peptides from mitochondria-containing stroma (MCS) is described. The process is independent of ubiquitin, but is sensitive to hemin and to heat treatment. Neither chloramphenicol nor EGTA inhibit. 50% of the activity is dependent on charged tRNA. The peptides released from MCS possess a molecular mass of about 1-5 kDa and are degraded to TCA-soluble compounds by a cytosolic protease system (fraction II) without ubiquitin.
