Growth of cells expressing Wbp1-Cub-PLV with
various Nub-fusions on agar plates lacking histidine. YG0673 cells
expressing Wbp1-Cub-PLV and either NubI-Alg5,
NubA-Alg5, or NubG-Alg5 from a 2-μm
plasmid or expressing Ost1-NubI,
Ost1-NubA, or Ost1-NubG from a 2-μm
plasmid were grown to logarithmic phase, spotted in serial 10-fold
dilutions on selective agar plates containing 0.2 mM CuSO4
+/− histidine and were incubated for 5 days at 30°C. YG0673
transformed with the vector pRS314 served as negative control.
