Thiamine‐regulated gene expression of Aspergillus oryzae thiA requires splicing of the intron containing a riboswitch‐like domain in the 5′‐UTR

Abstract
Exogenous thiamine regulates Aspergillus oryzae thiA, which is involved in thiamine synthesis. One of the two introns in its 5′‐untranslated region (5′‐UTR) contains motifs (regions A and B) highly c...
