Figure 4

A protease-deficient mutant of the 20S proteasome partially suppressed the M288Φ lethal phenotype. PRE4 and pre4-1 cells were transformed with the CUP1 promoter-regulated plasmid expressing wild-type Cdc48 (WT) and mutant Cdc48 with the replacement of E588Q and M288Y. The transformants were grown on media supplemented with 20 µM CuCl2 at 30 °C for 2 days.
