Comments
[?]
| FUNCTION | RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication. |
| CATALYTIC ACTIVITY | Reaction=ssDNA + n NTP = ssDNA/pppN(pN)n-1 hybrid + (n-1) diphosphate.; EC=2.7.7.101; |
| SUBUNIT | Monomer. Interacts with DnaB. |
| case <FTTag:zinc> | |
| COFACTOR | Name=Zn(2+); Xref=ChEBI:CHEBI:29105; 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. |
