Comments [?]

Function RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication.
Subunit Monomer. Interacts with DnaB.
case <FTTag:zinc>
Cofactor Zn(2+)
Note: Binds 1 zinc ion per monomer.
Domain Contains an N-terminal zinc-binding domain, a central core domain that contains the primase activity, and a C-terminal DnaB-binding domain.
end case
Similarity Belongs to the DnaG primase family.
