High impact information on ydeO

  • This acid resistance is partially abolished by deletion of ydeP, yhiE or ydeO, genes induced by EvgA overexpression [1].
  • The first class contains seven operons induced by EvgA overexpression in the absence of ydeO, an AraC/XylS regulator gene [1].
  • The induction of mdtEF by GlcNAc is not mediated by the evgSA, ydeO, gadX, and rpoS signaling pathways that have been known to regulate mdtEF expression [2].

Biological context of ydeO

  • Operons in the second class were induced by EvgA overexpression only in the presence of ydeO [1].
