Production of pABA in shake flask experiments of S. cerevisiae strains. WT = CEN.PK113-5D, PABA0 = CEN.PK113-5D Δtrp3 Δaro7 ARO4 K229L. PABA1–PABA5 are based on PABA0, with over-expression of additional ABZ1 and ABZ2 alleles on a plasmid expression vector as indicated on the figure (for full genotype cf. “Strain and plasmid construction” section)
