Structure of the Flavivirus helicase: implications for catalytic activity, protein interactions, and proteolytic processing.

abstract：:Measles virus (MV) is the type species of the Morbillivirus genus and its RNA-dependent RNA polymerase complex is comprised of two viral polypeptides, the large (L) and the phospho- (P) proteins. Sequence alignments of morbillivirus L polymerases have demonstrated the existence of three well-conserved domains (D1, D2,...
