Modulation of DNA polymerization PabPolB with Mg2+ or Ca2+ on primed-M13mp18 DNA template. (A) Structure of the primer-template mimic, consisting of a Cy5-labeled 32-mer primer annealed to the circular M13mp18 DNA template of 7249-nt in length. (B) Extension of the primed-M13mp18 DNA template at the indicated Mg2+ or Ca2+ concentrations. The starting primer (32-nt) and full-length product (7249-nt) are shown arrowed on the left. Product length is indicated under the gel lanes. (C) Extension of the primed-M13mp18 DNA template for the times shown above the gels (min) at fixed Mg2+ or Ca2+ concentrations (5 mM). The starting primer (32-nt) and full-length product (7249-nt) are shown arrowed on the left. Product length is indicated under the gel lanes.
