    Ligand Information



    Protein Summary

    The BT_3504 gene from Bacteroides thetaiotaomicron encodes a protein of unknown function. The structure contains two domains. The N-terminal domain adopts an immunoglobulin-like fold and contains an IPT/TIG signature (PF01833, residues 19-100). IPT/TIG domains are found in cell surface receptors and intracellular transcription factors. However, genome context of BT_3504 (BT_3505, putative outer membrane protein, probably involved in nutrient binding) suggests cell surface localization. The C-terminal domain adopts a 6-bladed beta-propeller fold and shows strong homology (HHPred probability 99.6%, E-value 6.5E-14, P-value 6.4E-18 over residues 140-460) to the SGL family (SMP-30/Gluconolaconase/LRE-like region, PF08450), the NHL repeat (NCL-1, HT2A and LIN-41 repeat, PF01436) and MRJP (major royal jelly protein, PF03022). In terms of structural similarity, the C-terminal domain gives the strongest hit with a calcium-dependent lactonase (PDB id: 2DG0) [Ref].


    See also BT_3679 (PDB id 3HRP).


    To do: compare ion coordination and active site residues between lactonase and BT_3504.

    1jof 3-Carboxy-cis,cis-muconate lactonizing enzyme catalytic residues HIS148 and GLU212 overlap well with GS13221D with conserved GLU334 and HIS354.
