DnaG_DnaB_bind DNA primase DnaG DnaB-binding
SMART ACC:	SM000766
Description:	DnaG_DnaB_bind defines a domain of primase required for functional interaction with DnaB that attracts primase to the replication fork. DnaG_DnaB_bind is responsible for the interaction between DnaG and DnaB.
InterPro ACC:	IPR013173
InterPro abstract:	Eubacterial DnaG primases interact with several factors to form the replisome. One of these factors is DnaB, a helicase. This domain has been demonstrated to be responsible for the interaction between DnaG and DnaB [ PUBMED:8308039 ]. This domain has a multi-helical structure that forms an orthogonal bundle [ expand Eubacterial DnaG primases interact with several factors to form the replisome.
