DNA primase, DnaB-helicase binding domain (IPR019475)

Short name: DNA_primase_DnaB-bd

Overlapping homologous superfamilies


Domain relationships



This entry represents the C-terminal region three-helical domain of DNA primase [PMID: 10741967]. Primases synthesise short RNA strands on single-stranded DNA templates, thereby generating the hybrid duplexes required for the initiation of synthesis by DNA polymerases. Primases are recruited to single-stranded DNA by helicases - this domain binds DnaB-helicase [PMID: 10873470]. It is associated with the Toprim domain IPR006171, which is the central catalytic core.
