Figure 5. Replicative abortion is independent of DnaG primase activity.
Replicative abortion is independent of DnaG primase activity. (a) DnaG is composed of three major domains: Zn-binding (ZBD), RNA polymerase, and DnaB-interaction domains. Mutant DnaG-P48 is a deletion of the C-terminal 148-residue interaction domain, and DnaG-C is a deletion of the N-terminal 433-residue primase domains as indicated by the brackets. (b) Processivities of leading-strand synthesis as obtained from single-molecule experiments under indicated conditions.
