This domain is found in DNA primase from Staphylococcus aureus (DnaG) and similar proteins predominantly found in firmicutes. DnaG is an RNA polymerase that catalyses the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication. This entry represents the helical bundle (HB) found at the C-terminal of the catalytic core of DnaG [1].	Domain

DNA primase (DNAG) is a a nucleotidyltransferase which synthesises the oligoribonucleotide primers required for DNA replication on the lagging strand of the replication fork. It can also prime the leading strand and has been implicated in cell division [1]. Primases comprise three domains: a zinc-binding domain at the N-terminal (Pfam:PF01807), a polymerase domain (catalytic core), and a domain that interacts with the replicative helicase (Pfam:PF01807). The catalytic core consists of an alpha+beta domain at the N-terminal (this entry) and a TOPRIM domain at the C-terminal (Pfam:PF13155) [1,2].	Domain
