Function[PRIA_ECOLI] Involved in the restart of stalled replication forks. Recognizes and binds the arrested nascent DNA chain at stalled replication forks. It can open the DNA duplex, via its helicase activity, and promote assembly of the primosome and loading of the major replicative helicase DnaB onto DNA. Is also involved in initiation of normal DNA replication in various plasmids and phages. Binds to branched DNA structures that resemble D-loops or to the primosome assembly site (PAS). Binds to DNA in two distinct modes, either dependent on or independent of the 3' terminus recognition.[1] [2] [3] [4] [5] [6] [7] [8] [9] [10] Evolutionary Conservation![]() Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedPriA, a DEXH-type DNA helicase, binds specifically to the 3' end of DNA through its N-terminal domain, and is a candidate sensor protein that recognizes arrested DNA replication forks in bacteria. We crystallized an N-terminal fragment of PriA in the absence and the presence of oligonucleotides to elucidate the structural basis for the specific recognition of the 3' terminus of DNA. Crystallization and preliminary crystallographic analysis of the N-terminal domain of PriA from Escherichia coli.,Sasaki K, Ose T, Tanaka T, Mizukoshi T, Ishigaki T, Maenaka K, Masai H, Kohda D Biochim Biophys Acta. 2006 Jan;1764(1):157-60.
