The recent outbreak of Zika virus (ZIKV) infection has caused global concern due to its link to severe damage to the brain development of foetuses and neuronal complications in adult patients. A worldwide research effort has been undertaken to identify effective and safe treatment and vaccination options. Among the proposed viral and host components, the viral NS2B-NS3 protease represents an attractive...
The NS2B-NS3 viral protease is an attractive drug target against Zika virus (ZIKV) due to its importance in viral replication and maturation. Here we report the crystal structure of protease in complex with a dipeptide inhibitor, Acyl-KR-aldehyde (compound 1). The aldehyde moiety forms a covalent bond with the catalytic Ser135 of NS3. The Arg and Lys residues in the inhibitor occupy the S1 and S2...
