(A) Domain comparison of A. fumigatus TrpE, PabaA and IcsA. Abbreviations: Ant, Anthranilate; Trp, Tryptophan.
(B) Northern expression analysis of trpE and icsA in A. fumigatus wild-type AF293. Ribosomal RNA was visualized by ethidium bromide staining as loading control. A. fumigatus strain AF293 was grown in liquid GMM containing 20mM glutamine as nitrogen source at 37 °C and 250 rpm for 24 h. Then mycelia were collected, transferred into solid GMM and grown in duplicates for the indicated time at 29 °C.
