EC 3.4.22.39 Adenain. [5 PDB entries]    
1avp

Reaction: Cleaves proteins of the adenovirus and its host cell at two consensus sites: -Yaa-Xaa-Gly-Gly-|-Xaa- and -Yaa-Xaa-Gly-Xaa-|-Gly- (in which Yaa is Met, Ile or Leu, and Xaa is any amino acid).
Comments: A cysteine endopeptidase from adenoviruses. Activity is greatly stimulated by the binding to the enzyme of an 11-residue peptide from the adenovirus capsid protein pre-VI at a site separate from the active site. Belongs to peptidase family C5.
