Viral security proteins: counteracting host defences 2010-11-09 .txt text/plain 8716 426 41 These proteins include: capsid proteins; an RNA-dependent RNA polymerase (3D pol ); a protein (VPg, or 3B) that serves as a primer for the initiation of RNA synthesis; an ATPase with a conserved superfamily 3 helicase motif (2C ATPase ) and an essential but poorly defined role in viral RNA replication; a chymotrypsin-like protease (3C pro ), which, as the mature protein or as a precursor, is a major factor in polyprotein processing; two hydrophobic membrane-binding proteins (2B and 3A) that participate in the generation of a virus-friendly environment; and, flanking the precursor of the capsid proteins, one or two highly variable proteins (L and 2A), the structure and functions of which are the subject of this Review. ./cache/cord-325230-3kg4oe4g.txt ./txt/cord-325230-3kg4oe4g.txt
