    Protein Summary

    NP_721579.1 is another example of a unexpected structural similarity to beta-lactamase inhibitory proteins (BLIP) which already include 1XXM, 1S0W, 1JTG, 2G2U, 2G2W and 2B5R, as well as our own recent structure, 3due. All of structures are involved in beta-lactamase inhibitor complex. The N-terminal of NP_721579.1 orients in the same way as the other structures. NP_721579.1 is a monomer in solution according to the calculation of interface interaction (PISA). During the refinement, there were no ligand or metal ions observed and modeled in the structure.
