    Protein Summary

    The CHU_0679 gene codifies for the YP_677306.1 sequence that belongs to the DNA damage inducible (din) B group (PF05163). It shows the conserved catalytic triad (H52--//--H148---H152) involved in metal (Ni) chelation. Study of its genome context provides a very weak hit (score 0.46) with the DeoR family of transcriptional regulators (YP_677307).

     

    SCOP classifies 2qnl in the all-alpha class, DinB/YfiT-like putative metalloenzymes superfamily, DinB-like family. The highest structural similarity (FFAS scr=-21; Dali Z-scr=14) is observed with 3di5, a putative enzyme with Ni bound and coordinated by a conserved His triad  (H48, H127, H131). A second hit (HHpred P-val=1e-26; FATCAT P-val=1e-8) is with 1rxq, a putative metal dependent hydrolase member of the YfiT family crystallized with Ni bound to positions H67 and H164 together with two ordered water molecules [Ref].
