Webthe DNA substrate. However, these two residues are 16.1 Å apart and oriented differently in the conserved p58C structure (Fig. 1, A and B). Con-sequently, results of CT and DNA-binding exper-iments are not applicable to WT primase. DNA substrates used by O’Brien et al.inthe binding and CT experiments are biologically ir-relevant. Both the 5 ... DnaG is a bacterial DNA primase and is encoded by the dnaG gene. The enzyme DnaG, and any other DNA primase, synthesizes short strands of RNA known as oligonucleotides during DNA replication. These oligonucleotides are known as primers because they act as a starting point for DNA synthesis. DnaG catalyzes the synthesis of oligonucleotides that are 10 to 60 nucleotides (the fundamental unit of DNA and RNA) long, however most of the oligonucleotides synthesized are …
