Abstract
Hepatitis B virus core gene products can adopt different conformations to perform their functional roles. In this issue of Structure, DiMattia and colleagues show the crystal structure of immuno-modulating HBeAg and thereby reveal the similarities and differences between it and HBcAg, the variant found in virions.
摘要
乙型肝炎病毒核心基因产物可以采用不同的构象来发挥其功能作用。在本期的《结构》杂志中，DiMattia 及其同事展示了免疫调节 HBeAg 的晶体结构，从而揭示了它与在病毒粒子中发现的 HBcAg 变体之间的相似之处和不同之处。
