詳細 | The NS3 protease domain, residues 1-181 of NS3, exists in a complex with an NS4a peptide and an inhibitor. There is a dimer of the NS3 domain-NS4a peptide complex, but only one monomer (Chains A and B) have the inhibitor bound to the active site. This dimer is the component of the asymmetric unit. In vivo, the protease domain is part of a multi enzyme protein (having both protease and helicase activities). The NS3 protease domain with the NS4A peptide is known to be catalytically active in the absence of the helicase domain, although it is not known whether it is active as a monomer or dimer. |
