Intermediates in plasmid pT181 DNA replication.

S Majumder1, R P Novick.   

Abstract

Staphylococcus aureus plasmid pT181 is thought to replicate via an asymmetric rolling-circle mechanism. By studying pulse labeled replicative intermediates, here we report that pT181 replication involves: (1) a post-replicative hypersupercoiled monomer and (2) a partially replicated intermediate which lacks superhelicity but is unlike a typical rolling-circle intermediate in that only nascent strands of less than unit length are released by alkali denaturation. A model for pT181 replication is proposed to accommodate this apparent discrepancy.
