| Abstract |
PriA protein, a DEXH-type helicase with C2C2 zinc-finger motifs, plays essential roles in RecA-dependent modes of Escherichia coli chromosomal DNA replication, namely inducible and constitutive stable DNA replication (iSDR and cSDR respectively, which may be initiated from a D-loop or R-loop structure), and in repair of double-stranded DNA breaks generated by various genotoxic agents or spontaneously during the course of DNA replication. However, the roles of ATPase/DNA helicase activities in functions of PriA are not well understood. |
