چکیده انگلیسی
The Zika virus (ZIKV) genome encodes a polyprotein that can be post-translationally processed into functional viral proteins. The viral protease is indispensable in the maturation of viral proteins. The Zika protease comprises of two components crucial for catalysis. The N-terminal region of NS3 contains the catalytic triad and approximately 40 amino acids of NS2B are essential for folding and protease activity. NS2B is a membrane protein with transmembrane domains that are critical for the localization of NS3 to the membrane. In this study, we expressed and purified full-length NS2B from ZIKV in E. coli. Purified NS2B was then reconstituted into lyso-myristoyl phosphatidylglycerol (LMPG) micelles. It was found that compared to wild type NS2B, NS2B C11S mutation in LMPG exhibited dispersed cross peaks in the 1H15N-HSQC spectrum, thereby suggesting the feasibility for structural characterization using solution NMR spectroscopy.
