CC   -!- FUNCTION: RNA polymerase that catalyzes the synthesis of short RNA
CC       molecules used as primers for DNA polymerase during DNA replication.
CC       Also part of the exosome, which is a complex involved in RNA
CC       degradation. Acts as a poly(A)-binding protein that enhances the
CC       interaction between heteromeric, adenine-rich transcripts and the
CC       exosome. {ECO:0000255|HAMAP-Rule:MF_00007}.
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_00007};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00007};
CC       Note=Binds two Mg(2+) per subunit. {ECO:0000255|HAMAP-Rule:MF_00007};
CC   -!- SUBUNIT: Forms a ternary complex with MCM helicase and DNA. Component
CC       of the archaeal exosome complex. {ECO:0000255|HAMAP-Rule:MF_00007}.
CC   -!- SIMILARITY: Belongs to the archaeal DnaG primase family.
CC       {ECO:0000255|HAMAP-Rule:MF_00007}.
