Display the word mapDisplay the reaction diagram Show all sequences 3.4.21.91more characterization of structural determinants necessary for activation of the enzyme by the NS2B cofactor. Alanine substitutions at residues Trp62, Leu75, and Ile79 in the NS2B cofactor result in marked effects on autoprocessing at the NS2B/NS3 site. The activity of the mutant NS3 protease with the synthetic peptide substrate Gly-Arg-Arg-4-methylcoumarin 7-amide is mainly affected by significantly reduced kcat values 666187

To function as an active enzyme, the NS3 protease requires the NS2B cofactor. NS2B is an integral membrane protein of 14 kDa that contains three domains: two trans-membrane segments located at the N- and C-termini and a central region of 47 amino acids (spanning amino-acids 49-96) that acts as an essential protein cofactor of the NS3 protease 752513

NS2Bc departs from NS3p in the open conformation, but it forms tight interactions with NS3p in the closed conformation 752653

The NS2B cofactor region from Zika virus protease is essential for recognition of host cell substrates. Replacing the NS2B region in another flavivirus protease enabled recognition of novel Zika-specific substrates by hybrid proteases, suggesting that the cofactor is the principal determinant in ZVP substrate selection 752362
