Experimental details: Figure 5 IC 50 of alpha-naphthoflavone (ANF) for the inhibition of CYP1A1 enzyme expressed within yRD + and yRD - :: Bax cells. ANF's IC 50 for inhibition of CYP1A1 enzyme that was expressed in live cells. The cells that were used were from strains ( A ) yRD + (+CPR) and ( B ) yRD - :: Bax (-CPR). CYP1A1 enzyme expression was driven by the ethanol-inducible ADH2 promoter (ADH2p). In yRD - cells, Bax expression was driven by the GAL1 promoter (GAL1p), which was de-repressed in ethanol. Recombinant cells were grown for 18 h in YPD liquid medium containing glucose, allowing for around 6 h of induction and de-repression of ADH2p and GAL1p in ethanol (it takes ~12 h for glucose to be utilized and entirely converted to ethanol). Cells were harvested, washed in PBS-saline. The assay included 1 x 10 7 washed cells and 7-ethoxyresorufin (7-ER) as substrates. The x -axis represents the values of the concentration of ANF in uM (ranges from 0.00001 to 3 uM) that were incubated with cells for 10 min, the y -axis relative fluorescence units of the fluorescent product formed.

Experimental details: Figure 4. Acr3 is a component of the Fps1 complex that regulates Fps1 in response to arsenicals. (A) As(V) treatment induces Fps1 closure in an acr3 Delta mutant. Rgc2-HA and Fps1-Myc were coexpressed (from p3151 and p3121, respectively) in a WT strain (DL3187), or an acr3 Delta mutant (DL4287). The strains were treated with 1 mM As(III) or 3 mM As(V) for the indicated times and processed for co-IP of Rgc2 with Fps1 using anti-Myc antibodies, as in Fig. 1 . (B) Acr3 associates with Fps1. A WT strain (DL3187) coexpressing Fps1-Myc (p3121) and Acr3-HA (p3470) or expressing only one protein was subjected to co-IP analysis using anti-HA antibodies. (C and D) BiFC analysis of Acr3 with known components of the Fps1 complex. An rgc1 Delta rgc2 Delta hog1 Delta strain (C; DL3219) coexpressing CFPC-Fps1 (p3216) and Acr3-CFPN (p3585) was visualized under a UV light source to reveal fluorescence complementation or under visible light (DIC).
