title: Expression of human papillomavirus type 6 E1, E2, L1 and L2 open reading frames in Escherichia coli.
abstract: Open reading frame (ORF) fragments (putative gene fragments) from human papillomavirus type 6b (HPV-6b) were inserted into the bacterial expression vector pHK413 to provide viral antigenic determinants. Approximately 86% of the entire L1 ORF, 82% of the E2 ORF, and 52% of the L2 ORF were expressed in Escherichia coli. The E1 ORF was cloned as two fragments. The constructions containing E1n (coding for the N-terminal region) and E1c (coding for the C-terminal region) expressed 27% and 16% of the E1 ORF, respectively. Protein encoded by the L1 ORF, but not that encoded by the L2 ORF, reacted with antibodies elicited by disrupted bovine papillomavirus. These reagents will be extremely useful in unravelling the HPV-6b replication cycle.
