E. coli ars promoter, arsR gene and lacZ
2006-10-12T11:00:00Z
2015-08-31T04:08:46Z
The ars promoter and arsR gene are derived from E. coli JM109 chromosomal DNA. The lacZ' minigene is derived from E. coli BL21 chromosomal DNA, since JM109 does not possess an intact lacZ gene.
Released HQ 2013
This biobrick contains the promoter region of the Escherichia coli chromosomal arsenic detoxification opern, including the arsR gene encoding the ArsR repressor protein required for inducibility of this promoter. This is fused to a lacZ' minigene encoding the N-terminal 77 amino acid residues of LacZ, sufficient to complement the lacZ-delta-M15 mutation. When introduced into an E. coli host strain carrying the lacZ-delta-M15 mutation, this construct results in lacZ expression in the presence of arsenate or arsenite anion. LacZ expression can be detected in various ways. This construct was designed for the detection of arsenate and arsenite in water samples.

Since this construct includes the arsR gene encoding the ArsR repressor which regulates the ars promoter, it requires no other promoter-specific functions. However, it will only give LacZ activity in a host expressing the E. coli lacZ-delta-M15 gene.

2015-08-31T04:08:46Z
The DNA was derived by PCR from E. coli BL21, which possesses an intact lacZ gene. Primers were designed based on sequence from GenBank accession J01636, GI:146575. A stop codon was artificially introduced to replace codon 78. The sequence reported here is derived by sequencing of the Biobrick construct.
Released HQ 2013
This gene encodes the N-terminal 77 amino acid residues of LacZ. When expressed in an E. coli host carrying the lacZ-delta-M15 mutation, common in laboratory strains, it complements the delection resulting in the production of active LacZ, which can be detected by various means, including chromogenic substrates such as Xgal (5-bromo-4-chloro-3-indolyl-beta-D-galactoside) and ONPG (o-nitrophenyl galactoside).

Note that a stop codon was introduced to replace codon 78 of lacZ, resulting in production only of the N-terminal 77 amino acid residues of LacZ. This is sufficient to complement the lacZ-delta-M15 mutation commonly found in laboratory strains of E. col used for alpha-complementation.

E. coli chromosomal ars promoter with arsR repressor gene
2006-10-12T11:00:00Z
2015-08-31T04:08:46Z
The DNA was derived by PCR using genomic DNA from E. coli JM109. Primers were designed based on the sequence reported by Diorio et al (1995), J. Bacteriol 177 (8), 2050-2056, Genbank accession X80057, GI:510824. The sequence given here is derived by sequencing the biobrick construct.
Released HQ 2013
This part consists of the promoter of the E. coli JM109 chromosomal arsenic detoxification operon (ars operon), including the ArsR repressor binding site and the arsR gene encoding the arsR repressor protein, together with its ribosome binding site. Addition of any other genes to the 3' end of this part will result in their expression being dependent on the presence of sodium arsenate or sodium arsenite. Arsenite or arsenite anion binds to the repressor protein ArsR, resulting in inability to repress the promoter. Based on our experiments, a concentration of 1 micromolar sodium arsenate in LB is sufficient for essentially full expression, though this will vary according to conditions.

Note that this sequence includes the arsR gene encoding the ArsR repressor protein, which is thus negatively autoregulated. No additional parts are required for arsenate-induced expression from this part. In principle, this part should also function in hosts other than E. coli.
