Protein attributes

Sequence length	164 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	This protein is required for primosome-dependent normal DNA replication; it is also involved in inducing stable DNA replication during SOS response. It forms, in concert with dnaB protein and other prepriming proteins dnaC, N, N', N'' a prepriming protein complex on the specific site of the template DNA recognized by protein N' By similarity.
Sequence similarities	Belongs to the dnaT family.
