FIG 1.

(A) Cartoon representations of the multimerization domain of Nipah virus P, with the dimensions, N and C termini, and residues involved in kinking indicated. (B) Cartoon representations of the multimerization domains of P from three other paramyxoviruses, Sendai virus, measles virus, and mumps virus, drawn on the same scale as Nipah virus P. Termini and residues involved in kinking of the central helices are indicated. (C) Cartoon representations of the multimerization domains of P from two rhabdoviruses, vesicular stomatitis virus and rabies virus. Both domains are dimers in solution and crystallized as dimers, but vesicular stomatitis virus has been shown to form a tetramer in the context of the RNA replication machinery (48, 49).
