the Escherichia coli Replication Restart Primosome
PDB Code: 1txy
Classification: DNA binding protein
Exp. Method: X-ray Diffraction
Structure : Primosomal replication protein N
Chain : a, b. Engineered: yes
Source: Escherichia coli. Bacteria. Gene: prib,
b4201. Expressed in: escherichia coli.
Resolution: 2.0 À
R-factor : 0.260 (Statistical factor)
R-free: 0.285 (Statistical factor)

Further Work dimer, only Lys82 is positionally conserved with a lysine residue of SSB involved in contacting nucleic acid, Lys87. Located at the base of the L45 loop, PriB Lys82 appears to be in a prime position to make contacts with ssDNA (Figure 4A).
