Enzyme Function | FUNCTION: Assembly protease promotes icosahedral procapsid assembly. Autocatalytic cleavage may release the capsid scaffolding protein. The protease domain catalyzes the cleavage of the capsid scaffolding protein after complete procapsid formation. Assembly protease and cleavages products are evicted from the capsid before or during DNA packaging.; FUNCTION: Scaffolding protein Nu3 promotes icosahedral procapsid assembly. Acts by binding the major capsid protein gpE and multimerizing in interaction with portal dodecamer, thereby placing gpE in a context facilitating icosahedral procapsid formation. Cleaved by capsid assembly protease C after capsid completion. The cleavages products are evicted from the capsid before or during DNA packaging. |
