Optimization of parameters for the primase-pyrophosphatase assay. (A) Activity of primase at varied DNA concentrations. (B) Primase activity assessed in presence of divalent metals salts at 2 mM concentration. (C) Primase activity with buffers at pH range 6–10. (D) Time course representation of the priming reaction over period of 0-70 min. (E) Rate PPi released by primase as a function of NTP concentrations. The experiments were conducted over a duration of 30 min.
