General Information

General Information Comment Organism
physiological function in the presence of the helicase DnaB the size distribution of primers is different, and a range of additional smaller primers are also synthesized. Mutations E15A, Y88A, and E15A Y88A in DnaB bind DnaG but are not able to modulate primer size, whereas the R195A/M196A mutant inhibits the primase activity Geobacillus stearothermophilus
