Nitrogen utilization growth assay of S. cerevisiae mutants gap1Δdip5Δ and gap1Δssy1Δ complemented with putative GAP-encoding genes of F. fujikuroi (FFUJ_01137, FFUJ_05331, FFUJ_09118, FFUJ_11370) and PcGAP1 of P. chrysogenum. Fresh cells of tested yeast strains were adjusted to an optical density of 1 and (A) plated on yeast minimal agar with 1 mM citrullin (Cit), 10 mM aspartate (Asp), 10 mM phenylalanine (Phe), 1 mM tyrosin (Tyr) or 10 mM isoleucine (Ile) or (B) a series of 10-fold dilutions (left to right) were dropped on yeast minimal agar with 1 mM ammonium sulfate ((NH4)SO4) or glutamate as sole nitrogen source. Plates were incubated for 4 days at 30°C.
