    Protein Summary

    Pfam update:This sequence is now obsolete. I dont understand this comment - this protein shows up both in NCBI (http://www.ncbi.nlm.nih.gov/protein/YP_001815198.1) and UniProt (http://www.uniprot.org/uniprot/B1YEL3). In the other hand, its is not included in NCBI NR database.

    Gene Exig_2733 from Exiguobacterium sp. 255-15 encodes the YP_001815198.1 protein with 169 residues belonging to Pfam DUF2529 family ( PF10740). It is present as a dimer in the crystal structure and crystal packing analysis suggests that this dimer should be the stable oligomeric form in solution.

    DALI suggests that the structure is similar to phosphoheptose isomerase. The superposition of 3jx9 (light green) with (putative) phosphoheptose isomerases - 3cvj (light blue) and 3bjz (light pink) - are shown below.

    The biological unit of 3jx9 and 1cvj is a dimer; in contrast, the biological unit of 3bjz is a tetramer.
