CC -!- FUNCTION: Catalytic subunit of DNA primase, an RNA polymerase that
CC catalyzes the synthesis of short RNA molecules used as primers for DNA
CC polymerase during DNA replication. The small subunit contains the
CC primase catalytic core and has DNA synthesis activity on its own.
CC Binding to the large subunit stabilizes and modulates the activity,
CC increasing the rate of DNA synthesis while decreasing the length of the
CC DNA fragments, and conferring RNA synthesis capability. The DNA
CC polymerase activity may enable DNA primase to also catalyze primer
CC extension after primer synthesis. May also play a role in DNA repair.
CC {ECO:0000256|HAMAP-Rule:MF_00700}.
CC -!- FUNCTION: RNA polymerase that catalyzes the synthesis of short RNA
CC molecules used as primers for DNA polymerase during DNA replication.

CC -!- SUBUNIT: Heterodimer of a small subunit (PriS) and a large subunit
CC (PriL). {ECO:0000256|HAMAP-Rule:MF_00700}.
CC -!- SIMILARITY: Belongs to the eukaryotic-type primase small subunit
CC family. {ECO:0000256|ARBA:ARBA00009762, ECO:0000256|HAMAP-
CC Rule:MF_00700, ECO:0000256|RuleBase:RU003514}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
