    Protein Summary

    Gene Reut_B5534 from Ralstonia eutropha jmp134 encodes the YP_299723.1 protein without a defined Pfam group yet. Based on its co-ocurrence, STRING provides a 0.75 scored hit with the histidine kinase YP_728475.

    Structurally, 3iuz is similar (Dali Z-scr=19) to 2rjb with an 18% of sequence identity and a rmsd of 2.4A for 320 carbon alpha superimposed. 3iuz has less insertions. Of note is that the metal binding site in 2rjb is conserved in 3iuz structure: H81, H237, E303. Other nearby residues are also highly conserved. Thus, it appears that 3iuz and 2rjb have similar function, likely metal hydrolases. However, no metal was detected in 3iuz.


    Note from Pfam: This is now in family DUF1338, PF07063, along with 2rjb.
