    Ligand Information



    Protein Summary

    This hypothetical protein, putative anti-sigma factor  from Parabacteroides distasonis ATCC 8503 is the first representation of PF04773 family (FecR protein). The  structure has two domains:  N - terminus has double-stranded beta-helix fold  (corresponding to PF04773) and C-terminus  can be described as  alpha(2)-beta-alpha-beta(2).


    The structure similarity search found this target has a similarity with Tail proteins: 3CDD (the structure alignment below, colored in cyan), 3D37 and 1WRU {PF05954, Phage late control gene D protein (GPD), about 9% seq. id.}
