Biology
LexRO
LexRO is a synthetic light-switchable repressor, based on a novel LOV light sensor domain, RsLOV. In the darkness, LexRO dimerizes and binds to its cognate operator sequence to repress promoter activity. Upon light exposure, the LexRO dimer dissociates, causing dissociation from the operator sequence, and initiates gene expression.
SD7
A SD sequence upstream of LexRO encoding gene. SD7 is a ribosome binding site on the genome , which is capable of recruiting ribosomes in engineered E. coli.
ccdB
ccdB gene is located on the Escherichia coli F-factor plasmid and is part of the toxin-antitoxin system encoded by the ccd operon, responsible for plasmid maintenance during cell division. ccdB encodes a toxic protein that acts as a DNA gyrase poison. It can bind DNA gyrase to the broken double-stranded DNA, leading to cell death.
ccdA
ccdA is the gene found within the ccd operon, encoding the antidote protein (CcdA) that protects cells from the toxic effects of CcdB. CcdA protein is easily degraded by Lonprotease.The cell loses the ccdA gene due to the loss of the F plasmid, causing the cell to succumb to the toxicity of CcdB.
