[20] Cleavage of LexA repressor

1994
Publisher Summary This chapter examines cleavage of LexA repressor. In normally growing cells, about 20 SOS genes are turned off by the LexA repressor. On inducing treatments, LexA undergoes specific proteolytic cleavage; cleavage inactivates LexA and leads to derepression of the SOS genes. This specific cleavage reaction is of biological interest as

Secondary structure of the repressor

Biochemical and Biophysical Research Communications, 1972
Studies on highly purified repressor of the lac operon in Escherichia, coli by optical rotatory dispersion and circular dichroism has led to an estimate that it contains 33–38% of α-helix and 18–27% of β-structure. Effect of urea and 2-chloroethanol on the secondary structure of the repressor was studied.

ABI4: versatile activator and repressor

Trends in Plant Science, 2013
The ABSCISIC ACID INSENSITIVE4 (ABI4) gene was discovered to be an abscisic acid (ABA) signaling responsive transcription factor active during seed germination. The evolutionary history of the ABI4 gene supports its role as an ABA signaling intermediate in land plants.

lac repressor-operator interaction. Analysis of the X86 repressor mutant

Journal of Molecular Biology, 1976
Abstract In vitro measurements show that the X86 repressor, which has an increased affinity for the lac operator as compared to wild-type repressor, also has an increased affinity for non-operator sites on Escherichia coli DNA. The rate constant of association of repressor and operator is decreased by E.
