Figure 5. The DnaX Complex Enhances the Efficiency By Which Leading-strand Synthesis is Reinitiated Downstream of a Lesion.
(A) DnaG titration following column isolation of ERIs. Reactions were conducted for 6 min on the CPD-A template.
(B) Column-isolated replication reactions using the CPD-A template and 1 μM DnaG in the presence or absence of DnaX-γ3 complex that was added 45 sec post EcoRI.
(C) Column-isolated replication reactions conducted at 250 nM DnaG with the CPD-A template. DnaX-γ3 complexes (2.5 nM) were added at different time points following EcoRI addition.
* ERIs that are labeled but not extended.
