Remark 351 | The biomolecule is most probably a monomer. Nevertheless, it is notable that the same dimer ... The biomolecule is most probably a monomer. Nevertheless, it is notable that the same dimer appears in the two crystal forms (1N7U and 1N7V). Although the buried surface per subunit in the dimer is ~1,206 A**2, which is relatively substantial, it only represents ~5.5% of the surface area of the P2 monomer. Rate zonal centrifugation, gel filtration, cross-linking, sedimentation equilibrium and low angle X-ray scattering strongly suggest that P2 is a monomer in solution. Furthermore, dynamic light scattering measurements indicated a monodisperse solution with an apparent molecular weight of 79 kDa, which is in reasonable agreement with that for the monomer (63.9 kDa). Nevertheless, P2 may form a loosely associated dimer when bound to the virion. |

Details | Biochemical evidence (gel filtration, low angle X-ray scattering, rate-zonal ultracentrifugation, and dynamic light scattering) indicate that P2 is monomeric, but a potential dimer appears in 3 crystal with different space groups and is obtained for this crystal form by the following symmetry operation: x, -y, -z |
