    Protein Summary

    394589 is an exopolyphosphatase (Ppx) with a novel domain swapping compared to other Ppxs (Figure 1). There are several Ppx structures (2flo, 1u6z,1t6d/1t6c,3cer, 2j4r). Ppx functions as a dimer, so domain arrangement is the same with the dimer despite the swapping (Figure 2).

     

    This protein is now in family PF02541.9 Ppx-GppA CL0108 along with other structures.
