Details | The asymmetric unit contains a dimer of the NS3 protease domain, with each monomer complexed with a molecule of the NS4a peptide. Both monomers of the NS3-4a complex have a structurally bound zinc atom. The Chain A monomer of the NS3-4a complex has a covalently bound ketoamide, with a linkage between Ser139 OG and C38 of the ketoamide. The NS3 protease domain is part of the larger NS3 protease-helicase protein that is catalytically active when complexed with the NS4a protein. The NS3 protease domain-NS4a peptide complex is catalytically active, but this is not the biologically active form. |
