[https://www.uniprot.org/uniprot/PRIS_PYRHO PRIS_PYRHO] Catalytic subunit of DNA primase, an RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication. The small subunit contains the primase catalytic core and has DNA synthesis activity on its own. Binding to the large subunit stabilizes and modulates the activity, increasing the rate of DNA synthesis while decreasing the length of the DNA fragments, and conferring RNA synthesis capability. The DNA polymerase activity may enable DNA primase to also catalyze primer extension after primer synthesis. May also play a role in DNA repair.<ref>PMID:14750947</ref>

BACKGROUND: In chromosomal DNA replication, DNA primase initiates the synthesis of a dinucleotide on a single-stranded template DNA, and elongates it to form a primer RNA for the replicative DNA polymerase. Although the apo-structure of an archaeal primase has been reported, the mechanism of primer synthesis by the eukaryotic-type primase still remains to be elucidated. RESULTS: In this study, we present the crystal structure of the eukaryotic-type DNA primase from the hyperthermophilic archaeon (Pyrococcus horikoshii) with the uridine 5'-triphosphate (UTP). In the present primase-UTP complex, the primase binds the triphosphate moiety of the UTP at the active site, which includes Asp95, Asp97, and Asp280, the essential residues for the nucleotidyl transfer reaction. CONCLUSION: The nucleotide binding geometry in this complex explains the previous biochemical analyses of the eukaryotic primase. Based on the complex structure, we constructed a model between the DNA primase and a primer/template DNA for the primer synthesis. This model facilitates the comprehension of the reported features of DNA primase.
