The sos regulatory system of escherichia coli

Abstract. The SOS response in Escherichia coli involves the induction of a multioperon regulatory system, which copes with the presence of DNA lesions that interfere with DNA replication. Induction depends on activation of the RecA protein to cleave the LexA repressor of SOS operons. In addition to inducible DNA repair,Guidelines for submitting commentsPolicy: Comments that contribute to the discussion of the article will be posted within approximately three business days.

Abstract. Induction of several SOS functions by mitomycin C, bleomycin or thermal treatment of a recA441 mutant growing under nitrate respiration conditions was studied in Escherichia coli. Mitomycin C caused inhibition of cell division, induction of prophages and expression of umuC gene but like in aerobically growing cells, it did not trigger the cessation of cell repiration.

Galligan Biology Department Reed the sos regulatory system of escherichia coli Review The SOS regulatory system of Escherichia coli. The RecA441 protein can be activated in vitro by a broader spectrum of oligonucleotides and polynucleotides than can the wildtype RecA protein, and it binds ATP and ATPyS more tightly (McEntee and Weinstock, 1981; Phizicky and Roberts, 1981).
