Abstract:The lytic replication of bacteriophage P1 requires RepL expression and the lytic stage origin, oriL, which is postulated to be located within repL gene sequence. The exact sequence of P1 oriL and the mechanism(s) of RepL-mediated DNA replication, however, are not fully understood. By using repL gene expression to induce DNA replication of a gfp and a rfp reporter plasmids, we demonstrated that synonymous base substitution in an adenine/thymidine-rich region of repL gene sequence, termed AT2, significantly inhi… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
