    Protein Summary

    Pfam update: the sequence of this target falls into DUF296.


    Gene Reut_B5223 from Ralstonia eutropha jmp134 encodes the protein YP_299413 that belongs to the DUF296 (PF03479) with an AT-hooking motif for possible DNA binding.

    Pre-SCOP classifies 3HWU inside the alpha+beta class, AF0104/ALDC/Ptd012-like superfamily, AF0104 family.

    DALI suggests 3HWU is structurally similar to 3HTN (Z-scr=20), 2DT4 (Z-scr=18), 2H6L (Z-scr=18), 2NMU (Z-scr=16), and 2P6Y (Z-scr=16). In the 3hwu structure there is a piece of unknown electron density observed near to His 117, His119 and His 133. Based on directly superposition comparison, the His 117, 119 and 133 should be structurally conserved for metal-binding.  The likely biomolecule of 3hwu is a trimer.




    Figure 1. 3hwu monomer has a conserved active site for metal-binding.



    Figure 2. The biomolecule of 3hwu is likely a trimer.





    Figure 3. H117, H119 and H133 are conserved for metal-binding in the 3hwu structure.
