Previous studies have indicated that the ATP-requiring conjugation of ubiquitin with proteins plays a role in the energy-dependent degradation of intracellular proteins. To examine whether such conjugates are indeed intermediates in protein breakdown, conjugates of 125I-labeled lysozyme with ubiquitin were

By affinity chromatography of a crude reticulocyte extract on ubiquitin-Sepharose, three enzymes required for the conjugation of ubiquitin with proteins have been isolated. One is the ubiquitin-activating enzyme (E1), which is covalently linked to the affinity column in the presence
