    Protein Summary

    The following content is uploaded from Kevin Kai Jin's refinement summary, more discussion about these Eut protein structures will be continuously added very soon.

    Pfam update: On building, this rapidly overlapped with ANF_receptor PF01094.

    Gene YP_556174.1 encodes a protein with 399residues from Burkholderia xenovorans lb400 with Isoelectric Point of 9.17, which belongs to PF01094 receptor family ligand binding region.  The NCI blast sequence alignment also indicates that this protein carries putative conserved domains belonging to the superfamily of type 1 periplasmic binding protein.   A structural homolog search via SSM and Dali sever show that this protein is a structural homolog to those ABC protein structures.  The interface interaction suggests that the biomolecule of this protein be a dimer. 


    Figure 1. Protein YP_556174.1 is monomer for its biomolecule assignment.




    Figure 2. Protein YP_556174  is structural homolog

    to AMIDASE OPERON (PDB ID 1PEA, magenta) and

    another ABC protein from JCSG (PDB ID 3I09,yellow).





    Figure 3. Protein YP_556174 consists of two domains.

    Based on its function annotation, part of density at domain

    interface is modeled as the phosphate moiety from ADP.
