Table 1. AmB resistance mediated by PMP3 is not dependant on HSP90.
Strain | MIC | ||
---|---|---|---|
AmB, μg/ml | Radicicol, μM | TBH, mM | |
BY4741/vector | 0.4 | 16 | 2 |
pmp3Δ/vector | 0.05 | 8 | 2 |

erg6Δ/vector | 1.6 | 2 | 0.5 |
MIC for AmB and radicicol was determined in SC-ura broth at 30°C. Sensitivity to oxidative stress was determined by dilution spotting on SC-ura agar medium with tert-butyl hydroperoxide (TBH) at 37°C. MIC is the concentration at which no growth was observed.
