    Protein Summary

    Gene mlr7391 from MESORHIZOBIUM LOTI encodes the NP_107719.1 protein with 117 residues. 
    The search results from NCBI sequence alignment indicate this hypothetic protein carries a fold belonging to the NTF2_like superfamily protein.  It classifies inside the SnoaL-like polyketide cyclase group (PF07366). It has been suggested as a structural homolog to 1NU3, 1SJW and 1TUH by FFAS and SSM.  There are 4 subunits in each asymmetric unit cell. The interface interaction indicates that the biomolecule of protein NP_107719.1 should be a dimer.



    Figure 1. Protein NP_107719.1  monomer carries the

    α/β-barrel folding core belonging to the NTF_2 superfamily.



    Figure 2. The biomolecule of NP_107719.1 (Green) should be a dimer based on interface interaction.




    Figure 3. The biomolecule of NP_107719.1 (Green) should be a structural homolog to  1TUH(cyan), 1SJW (magenta) and 1NU3(yellow).
