    Protein Summary

    The APE_0880a (APES039) gene from Aeropyrum pernix codes for the NP_147569.1 protein, a small polypeptide of 95 amino acids with a weak hit (e-val=0.01) with the winged helix DNA binding domain group (PF07381).

    SCOP classifies this protein in the all-alpha class, winged helix DNA-binding domain superfamily, F93-like family. DALI top hits are with the AF_1382 protein PDB:2qvo (Z=11) and the putative transcription factor PDB:3df8 (Z=11). It is suggested this protein is a dimeric bacterial transcription factor of unknown specificity. Taking the dimer gives a very good hit for PDB:1tbx, a viral winged helix DNA binding protein [Ref].
