ABSTRACT
Objective To identify specific peptides binding to hepatitis B virus ( HBV) DNA pol-ymerase TP region ( HBP-TP) and to study their effects on HBV replication. -ethods The phage polypep-tide display library was screened using the HBP-TP recombinant protein expressed in Escherichia coli as a substrate to obtain the specific phage, the polypeptide region of which was then sequenced. Polypeptide se-quences with a repetition rate greater than 10% were counted and commercially synthesized. Changes in HBV replication were detected after treatment of HBV-expressing cells with synthetic peptides as drugs. Re-sults Eight peptides targeting HBP-TP recombinant protein were screened out from the phage display librar-y. One of the peptides was found to have a significant inhibitory effect on HBV replication at cellular level. Conclusions A HBP-TP protein-targeting polypeptide with an inhibitory effect on HBV replication was ob-tained.
