== Publication Abstract from PubMed == | |||
Zika virus (ZIKV) has rapidly emerged as a global public health concern. Viral NS2B-NS3 protease processes viral polyprotein and is essential for the virus replication, making it an attractive antiviral drug target. We report crystal structures at 1.58-angstrom resolution of the unlinked NS2B-NS3 protease from ZIKV as free enzyme and bound to a peptide reversely oriented at the active site. The unlinked NS2B-NS3 protease adopts a closed conformation in which NS2B engages NS3 to form an empty substrate-binding site. A second protease in the same crystal binds to the residues K14K15G16E17 from the neighboring NS3 in reverse orientation, resisting proteolysis. These features of ZIKV NS2B-NS3 protease may accelerate the discovery of structure-based antiviral drugs against ZIKV and related pathogenic flaviviruses. | |||
