Structural Insight into the DNA-Binding Mode of the Primosomal Proteins PriA, PriB, and DnaT

Table 2

Examples for some different PriA-directed primosome systems.

	PriA size; (amino acid residues)	Partner proteins found in NCBI
Escherichia coli and Klebsiella pneumoniae	731	PriB, PriC, DnaT, DnaC, DnaB helicase, and DnaG
Staphylococcus aureus	802	DnaD, DnaB, DnaI, DnaC helicase, and DnaG
Pseudomonas aeruginosa	739	Only DnaB helicase and DnaG are found

PriA is conserved in bacteria, but its primosomal partners are not.
