CC   -!- FUNCTION: RNA polymerase that catalyzes the synthesis of short RNA
CC       molecules used as primers for DNA polymerase during DNA replication.
CC       {ECO:0000255|HAMAP-Rule:MF_00974}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ssDNA + n NTP = ssDNA/pppN(pN)n-1 hybrid + (n-1) diphosphate.;
CC         EC=2.7.7.101; Evidence={ECO:0000255|HAMAP-Rule:MF_00974};
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00974};
CC       Note=Binds 1 zinc ion per monomer. {ECO:0000255|HAMAP-Rule:MF_00974};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00974};
CC       Note=Binds two Mg(2+) per subunit. {ECO:0000255|HAMAP-Rule:MF_00974};
CC   -!- SUBUNIT: Monomer. Interacts with DnaB. {ECO:0000255|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:0000255|HAMAP-Rule:MF_00974}.
CC   -!- SIMILARITY: Belongs to the DnaG primase family. {ECO:0000255|HAMAP-
CC       Rule:MF_00974}.
