priS

Gene
priS
Protein
DNA primase small subunit PriS
Organism
Methanosarcina barkeri (strain Fusaro / DSM 804)
Length
414 amino acids
Function
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.
Similarity
Belongs to the eukaryotic-type primase small subunit family.

Gene

Protein
DNA primase small subunit PriS
Organism
Sulfolobus islandicus (strain Y.N.15.51 / Yellowstone #2)
Length
330 amino acids
Function
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.
Similarity
Belongs to the eukaryotic-type primase small subunit family.
