The LexA repressor or LexA (Locus for X-ray sensitivity A) is a transcriptional repressor (EC 3.4.21.88) that represses SOS response genes coding primarily...

stimulated by single-stranded DNA, is involved in the inactivation of the repressor (LexA) of SOS response genes thereby inducing the response. It is an error-prone...

replication of the lambda genome (OP). Cro dominates the repressor site (see "Repressor" section), repressing synthesis from the PRM promoter (which is a promoter...

co-protease function in the autocatalytic cleavage of the LexA repressor and the λ repressor. The RecA protein binds strongly and in long clusters to ssDNA...

Lexa in Wiktionary, the free dictionary. Lexa may refer to: Lexa, Arkansas, a city in Phillips County, United States Repressor lexA Lexa (name) Lexa (singer)...

which the LexA repressor binds to repress the transcription of SOS-induced proteins. SOS boxes are found near the promoter of various genes. LexA binds to...

the SOS response: lexA encodes a repressor for all the genes in the system, and recA encodes a protein able to cleave the LexA repressor upon activation...

activate LexA autoprotease activity, which ultimately leads to cleavage of LexA dimer and subsequent LexA degradation. The loss of LexA repressor induces...

Transcription of the SOS response genes is negatively regulated by the LexA repressor. LexA binds to the promoter of the UmuDC operon and inhibits gene transcription...

he cloned the E. coli LexA repressor and showed how it controlled the cell's response to DNA damage, used LexA as a repressor in yeast, and created fusion...
