Protease digestion of hepatitis A virus: disparate effects on capsid proteins, antigenicity, and infectivity.

Abstract:

:High concentrations of either trypsin or chymotrypsin caused nearly complete cleavage of capsid protein VP2 of hepatitis A virus but did not significantly reduce the infectivity, thermostability, or antigenicity of the virus. Chymotrypsin also had a lesser effect on VP1. These findings indicate the presence of a protease-accessible VP2 surface site which neither contributes significantly to the dominant antigenic site nor plays a role in the attachment of the virus to putative cell receptors.
