The RecA protein of Escherichia coli, which has crucial roles in homologous recombination, DNA damage repair, induction of the SOS response, and SOS mutagenesis, was found to catalyze assimilation of complementary RNA into a homologous region of a DN

Initiation of chromosome replication is a key event in the life cycle of any organism. Little is known, however, about the regulatory mechanisms of this vital process. Conventionally, the initiation mechanism of chromosome replication in microorganis

We examined the effects of mutations in the polA (encoding DNA polymerase I) and polB (DNA polymerase II) genes on inducible and constitutive stable DNA replication (iSDR and cSDR, respectively), the two alternative DNA replication systems of Escheri

Constitutive stable DNA replication (cSDR), which uniquely occurs in Escherichia coli rnhA mutants deficient in ribonuclease HI activity, requires RecA function. The recA428 mutation, which inactivates the recombinase activity but imparts a constitut

On the basis of the experiments carried out with rnhA224 mutants, we previously concluded that RNase HI is not essential for initiation of Escherichia coli chromosome replication at oriC (T. Kogoma, N.L. Subia, and K. von Meyenburg, Mol. Gen. Genet.

Upon induction of the SOS response in Escherichia coli, the mode of initiation of DNA replication is altered such that it can occur in the absence of normally required protein synthesis. This type of DNA replication has been termed induced stable DNA

Replication of plasmid pBR322 in Escherichia coli cells normally requires RNA synthesis and thus is sensitive to rifampin, an inhibitor of RNA polymerase. In cells induced for the SOS response, however, derivatives of pBR322 were found to replicate i

During SOS induction, Escherichia coli cells acquire the ability to replicate DNA in the absence of protein synthesis, i.e., induced stable DNA replication (iSDR). Initiation of iSDR can occur in the absence of transcription and DnaA protein activity

The evidence summarized above strongly suggests that E. coli cells deal with exposed double-stranded ends by a process that requires both homologous recombination and DNA replication functions. This process could lead to recombinant formation. Import
