peptide mapping of nv5 ( p91 ) and nv4 ( p67 ) from all these isolates using limited proteolysis with alpha-chymotrypsin and v8 protease revealed completely identical patterns , thus extending our observations that tbe virus seems to represent a very stable member of the flavivirus genus , which was based on the lack of variation found with the structural glycoprotein .
