Abstract

In the presence of dATP, glycerol, and Tris buffer, the DNA primase isolated from Thermococcus kodakaraensis catalyzed the formation of dAMP and two products that were identified as dAMP-glycerol and dAMP-Tris. These products were formed by the T. kodakaraensis p41 catalytic subunit alone and the T. kodakaraensis p41-p46 complex in the absence of a DNA template. They were not formed with preparations containing the catalytically inactive p41 subunit. Similar glycerol and Tris derivatives as well as dNMPs were also formed with dGTP, dCTP, or dTTP. The mechanism contributing to the formation of these products and its implications in the initiation reaction catalyzed by the T. kodakaraensis primase are discussed.
