Extended Data Fig. 5: Proteasomal activity is not affected by leucine.

a-b. Activity of cytosolic proteasome or proteasome associated with mitochondria. Mean ± sem, n = 3 independent biological replicates, unpaired two-tailed t-test. c. Experimental procedure of OMM protein isolation. Mitochondria were enriched followed by OMM protein isolation. The isolated OMM proteins were confirmed by the presence of the OMM protein VDAC2 and the absence of IMM protein MTCO1. Source numerical data and unprocessed blots are available in Source data.
