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}.
