RESUMO

The hepatitis B virus X gene product trans activates transcription from a variety of viral and cellular regulatory elements. We expressed the complete, nonfused X protein in Escherichia coli and showed it to be active in trans activating a human immunodeficiency virus long terminal repeat-linked chloramphenicol acetyltransferase reporter gene.
