The group of isozymes has been made into an enteric-coated capsule in the Hepatitis B Virus (HBV) infection remains a major health treatment of stroke over 20years. Here we show that one of problem worldwide despite the availability of a highly ef- the isozymes from E. fetida is able to recognize and degrade fective preventive vaccine. HBV genome codes several HBeAg, suggesting that lumbrokinase could be used as a distinct proteins, among which the non-particulate e-antigen potentialdrugtotargetHBeAginthetreatmentofhepatitisB. (HBeAg) is one of the important markers in HBVinfection. The isozymes of lumbrokinase were prepared by an ionic Sera containing HBeAg are highly infectious but those with columnfollowedbyaffinitychromatographywithagradient anti-HBeAg have little infectivity. The spontaneous or GuHCl (Figure S1A).
