CC ECO:0000256|PIRNR:PIRNR002811, ECO:0000256|PIRSR:PIRSR002811-1};
CC Note=Binds 1 zinc ion per monomer. {ECO:0000256|HAMAP-Rule:MF_00974,
CC ECO:0000256|PIRNR:PIRNR002811, ECO:0000256|PIRSR:PIRSR002811-1};
CC -!- SUBUNIT: Monomer. Interacts with DnaB. {ECO:0000256|HAMAP-
CC Rule:MF_00974}.
CC -!- DOMAIN: Contains an N-terminal zinc-binding domain, a central core
CC domain that contains the primase activity, and a C-terminal DnaB-
CC binding domain. {ECO:0000256|HAMAP-Rule:MF_00974}.
CC -!- SIMILARITY: Belongs to the DnaG primase family. {ECO:0000256|HAMAP-
CC Rule:MF_00974, ECO:0000256|PIRNR:PIRNR002811}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
