Confirmation that Pnp1 is the physiological purine nucleoside phosphorylase, Urh1 is the pyrimidine hydrolase, and Prm15 (Pgm3) is the phosphoribomutase. Ratio of metabolite levels in pnp1/urh1, pnp1, urh1 and prm15 (pgm3) strains versus wild-type strain during carbon starvation. Data are shown in heat map format, with each line reflecting the dynamics of the ratio of the metabolite levels in a particular strain versus wild-type strain. All reported values are log₂ transformed ratios; data are mean of duplicate samples at each time point.
