    Protein Summary

    [The following content, including  figures, is uploaded from Kevin Kai Jin's refinement summary, more discussion about this protein structure will be continuously added very soon]


    Pfam note: this protein is now incorporated into: AP_endonuc_2 PF01261 This family is part of the TIM barrell clan, and the family itself already has many structures resolved for it. The hit has a very high bit score. and best wishes


    Gene YP_426450.1 encodes a protein with 297 residues from RHODOSPIRILLUM RUBRUM ATCC 11170 with Isoelectric Point of 4.78, which belongs to PF01261 xylose isomerase with TIM alpha/beta barrel fold.  The NCI blast sequence alignment also indicates that this protein carries a  conserved domain of AP_endonuc_2, Xylose isomerase-like TIM barrel.  A structural homolog search via SSM and Dali sever show that this protein is a structural homolog to those xylose isomerase protein structures.  The interface interaction suggests that the biomolecule of protein YP_426450.1 be a dimer.
