Damage inducible ATP-dependent 3'->5' nuclease; 3'-5' exonuclease.

Transcriptional repressor of the SOS regulon; Represses dinA, dinB, dinC, recA genes and itself by binding to the 14 bp palindromic sequence 5'-CGAACNNNNGTTCG-3'; some genes have a tandem consensus sequence and their binding is cooperative. In the presence of single-stranded DNA, RecA interacts with LexA causing an autocatalytic cleavage which disrupts the DNA-binding part of LexA, leading to derepression of the SOS regulon and eventually DNA repair; autocleavage is maximal at pH 11 in the absence of RecA and ssDNA.

Multifunctional SOS repair factor; Multifunctional protein involved in homologous recombination, DNA repair and competence. Can catalyze the hydrolysis of (d)ATP in the presence of single-stranded DNA; prefers dATP at least in vitro, catalyzes the dATP-dependent uptake of single- stranded DNA by duplex DNA, and the dATP-dependent hybridization of homologous single-stranded DNAs (strand exchange). RecA-ATP cannot catalyze homologous DNA strand exchange; SsbA and DprA activate strand exchange by RecA-ATP. It interacts with LexA causing its activation and leading to its autocatalytic clea [...]

Single-strand DNA-binding protein; Plays an important role in DNA replication, recombination and repair. Binds to ssDNA and to an array of partner proteins to recruit them to their sites of action during DNA metabolism. Has a 20-fold higher affinity for ssDNA than SsbB; SsbA and DprA activate the homologuos DNA strand exchange function of RecA-ATP.

DNA topoisomerase I; Releases the supercoiling and torsional tension of DNA, which is introduced during the DNA replication and transcription, by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA- (5'-phosphotyrosyl)-enzyme intermediate and the expulsion of a 3'-OH DNA strand. The free DNA strand then undergoes passage around the unbroken strand, thus removing DNA supe [...]
