Abstact

Using energy and density guided Rosetta refinement to improve molecular replacement, we determined the crystal structure of the protease encoded by xenotropic murine leukemia virus-related virus (XMRV). Despite overall similarity of XMRV protease to other retropepsins, the topology of its dimer interface more closely resembles those of the monomeric, pepsin-like enzymes. Thus, XMRV protease may represent a distinct branch of the aspartic protease family.
