Comments [?]

case <OC:Halobacteriales> or <OC:Methanococcales> or <OC:Methanomicrobiales>
FUNCTION	RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication.
SUBUNIT	Forms a ternary complex with MCM helicase and DNA.
else
FUNCTION	RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication. Also part of the exosome, which is a complex involved in RNA degradation. Acts as a poly(A)-binding protein that enhances the interaction between heteropolymeric, adenine-rich transcripts and the exosome.
SUBUNIT	Forms a ternary complex with MCM helicase and DNA. Component of the archaeal exosome complex.
end case
CATALYTIC ACTIVITY	Reaction=ssDNA + n NTP = ssDNA/pppN(pN)n-1 hybrid + (n-1) diphosphate.; EC=2.7.7.101;
SIMILARITY	Belongs to the archaeal DnaG primase family.
