additional information
-
proteolytic activity within the M-PMV Pr95Gag-Pro precursor is effectively suppressed within an assembled immature capsid, but with addition of dithiothreitol, there is a dramatic increase in protease activity. The activation of the protease results in the cleavage of p17 from the Pr95 precursor as a primary event, followed by processing of the Gag polyproteins into other mature viral proteins
