    Summary
    WrbA was originally identified as a stationary phase TrpR-binding protein that affected the interaction of TrpR with its operator sites in vitro (Yang, 1993). [More information is available at EcoGene: EG11540]. The purified WrbA protein has NAD(P)H:quinone oxidoreductase activity . [More information is available at EcoCyc: EG11540].

    GeneRIFs: Gene References Into Functions

    What's a GeneRIF?
    1. Topologically non-equivalent residues undergo remarkably similar local structural changes upon Flavin Mononucleotide binding to WrbA or to flavodoxin, despite differences in multimeric organization and residue types at the binding sites.
      Title: Structural organization of WrbA in apo- and holoprotein crystals.
    2. Structural comparison of WrbA, flavodoxin, and Nqo1 indicates how the twisted open-sheet fold of flavodoxins is elaborated to form multimers that extend catalytic function from one-electron transfer between protein partners.
      Title: WrbA bridges bacterial flavodoxins and eukaryotic NAD(P)H:quinone oxidoreductases.
    3. N-terminus verified by Edman degradation on mature peptide
      Title: A stationary-phase protein of Escherichia coli that affects the mode of association between the trp repressor protein and operator-bearing DNA.
    4. FMN binding has a dramatic effect on WrbA thermal stability, shifting the Tm by approximately 40 degrees C.
