    • Sample_characteristics_ch1: The haploid prototrophic S. cerevisiae strain CEN.PK 113-7D (MATa) was obtained from Dr. P. Kötter, Frankfurt, Germany. Zinc-depleted cells were obtained by four serial transfers of yeast cells in shake flasks containing synthetic medium91 from which zinc was omitted, and subsequently mixed with glycerol (final concentration 20%), aliquoted and stored at -80 °C.
    • Sample_biomaterial_provider_ch1: L Hazelwood
    • Sample_treatment_protocol_ch1: Liquid nitrogen
    • Sample_growth_protocol_ch1: C)hemostat cultivation
    • Sample_growth_protocol_ch1: Steady-state chemostat cultures of S. cerevisiae CEN.PK113-7D strain were performed in a 2-liter fermenter (Applikon) with a working volume of 1 liter (van den Berg et al 1996) . These cultures were fed with synthetic medium (see below) which limited growth by carbon, nitrogen or zinc with all other growth requirements in excess and at constant residual concentration (Boer et al 2003). The dilution rate was set at 0.1 h-1. The pH was measured on-line and kept constant at 5.0 by the automatic addition of 2 M KOH using an Applikon ADI 1030 Biocontroller. The stirrer speed was set at 800 rpm. Anaerobic conditions were maintained by sparging the medium reservoir (0.05 liter.min-1) and the fermenter with pure nitrogen gas (0.5 liter.min-1). Norprene tubing and butyl septa were used to minimize oxygen diffusion into the anaerobic cultures (Visser et al 1990). The off-gas was cooled by a condenser connected to a cryostat set at 2 °C. Oxygen and carbon dioxide were measured off-line with an NGA 2000 Rosemont gas analyzer. Cultures were assumed to be in steady-state when, after 4 to 5 volume changes, culture dry-weight, glucose concentration, carbon-dioxide production rate and oxygen consumption rate varied by less than 2 % during one volume change (Ferea et al, 1999; Jansen etal 2004). Steady-state samples were taken after 10 generations at the latest to avoid strain adaptation due to long-term cultivation. Each cultivation condition was performed in triplicate.
    • Sample_growth_protocol_ch1: Growth media
    • Sample_growth_protocol_ch1: The synthetic media composition was based on that described by Verduyn (1992). In all chemostats except for those limited by carbon, residual glucose concentration was targeted to 17 g.liter-1 in order to sustain glucose repression at the same level. The media composition for aerobic cultivations was the following: for zinc-limited cultivation, 5.0 g.liter-1 (NH4)2SO4, 3.0 g.liter-1 KH2PO4, 0.5 g.liter-1 MgSO4•7H2O, 66 g.liter-1 glucose and 0.014 mg.liter-1 ZnSO4•7H2O.

    • Sample_molecule_ch1: total RNA
    • Sample_extract_protocol_ch1: Microarray analysis. Sampling of cells from chemostats and total RNA extraction was performed as previously described in Abbott et al. (2007). Probe preparation and hybridization to Affymetrix Genechip® microarrays were performed following Affymetrix instructions. The one-cycle eukaryotic target labelling assay was used, starting with 15 g of total RNA. The quality of total RNA, cDNA, cRNA and fragmented cRNA were checked using the Agilent Bioanalyzer 2100 (Agilent Technologies). Results for each growth condition were derived from three independent culture replicates.
