Comments: Genotype: λDE3 Δtig100 Δ(araD–araB)567 ΔlacZ4787(::rrnB-3) lacIP-4000(lacIQ) rph-1 Δ(rhaD–rhaB)568 hsdR514
KTD101(DE3) is a λDE3 derivative of the trigger factor deficient (Δtig) strain KTD101 from Puertas et al 2010 Protein Expression and Purification 74: 122–128, PMID 20600941.
Puertas et al 2010 showed that deletion of trigger factor in the parent strain KTD101 increased the level of secreted recombinantly expressed protein. This strain may also improve the level of protein expression in the periplasm and in the outer membrane. This derivative strain KTD101(DE3) now allows expression that is based on the widely-used T7 promoter.
The parent strain KTD101 was provided by François Baneyx at the University of Washington.
DE3 lysogenization is apparent from positive expression that was obtained for the BBA57 protein upon expression from the T7 promoter plasmid pBBA57-TEV-His12, as was shown in Figure S5C, lane 7, of Robertson et al, Sci Rep. 2019 Nov 26;9(1):17606. doi: 10.1038/s41598-019-53830-x.

Genetic Insert: ssb (W88C)
Vector Backbone Description: Vector Backbone:pET22b; Vector Types:Bacterial Expression; Bacterial Resistance:Ampicillin
Defining Citation: PMID:20350930
Comments: Please note- The numbering system used was for the mature natural wild-type ssb protein. The N-terminal methionine is quantitatively cleaved off in E. coli and was not numbered so all mutations will be off by 1 nucleotide (e.g., W89C = W88C).
The expressed protein is a single-cysteine variant of E. coli single-stranded DNA-binding protein, EcSSB, for subsequent labeling at the cysteine. The adduct with Cy3B maleimide has been used as a biosensor for single-stranded DNA in TIRF microscopy measurements.

Genetic Insert: ssb (G26C)
Vector Backbone Description: Vector Backbone:pET22b; Vector Types:Bacterial Expression; Bacterial Resistance:Ampicillin
Defining Citation: PMID:18599625
Comments: Please note: The numbering system used was for the mature natural wild-type ssb protein. The N-terminal methionine is quantitatively cleaved off in E. coli and was not numbered so all mutations will be off by 1 nucleotide (e.g., G27C = G26C).
The expressed protein is a single-cysteine variant of E. coli single-stranded DNA-binding protein, EcSSB, for subsequent labeling at the cysteine with one IDCC (N-[2-(iodoacetamido)ethyl]-7-diethylaminocoumarin-3-carboxamide) per subunit. This adduct is then used as a fluorescent single-stranded DNA (ssDNA) biosensor, having ~6-fold fluorescence increase on binding ssDNA with very high affinity.

Genetic Insert: pstS (A17C,I76G,A197C)
Vector Backbone Description: Vector Backbone:pET22b; Vector Types:Bacterial Expression; Bacterial Resistance:Ampicillin
Defining Citation: PMID:26199994
Comments: Please note- The numbering system used was for the mature natural wild-type PstS protein. The plasmid produces an extra N-terminal methionine so all mutations will be off by 1nt (e.g., A197C =A198C)
PstS ORF encoding the mature E. coli (A17C, I76G, A197C)PstS protein (PBPw) containing a stop codon at the end of the gene in pET22b (inserted between Nde1 and Xho1 sites in the MCS).
Expression produces MEA at the N-terminus of the mature PstS: So there is an extra M at the N-terminus over the natural, mature PstS. A stop codon was also added at the end of the sequence BEFORE the plasmid-derived His tag. This gives PLY at the C-terminus at the C-terminus of the expressed protein, as in the natural PstS. The amino-acid numbering has been left as based on positions in the natural, mature protein.
Usage
The expressed protein is a weak-binding variant of E. coli phosphate binding protein, PstS. It contains two cysteines (A17C, A197C) and a mutation to weaken binding (I76G). The gene encodes the mature protein without the N-terminal signal peptide, but with an N-terminal methionine. Subsequently the cysteines are labeled with 2 6-iodoactemidotetramethylrhodamines per molecule. This adduct is then used as a phosphate biosensor, having up to 9-fold fluorescence intensity increase on binding inorganic phosphate, with a low dissociation constant so inorganic phosphate can be measured in the tens of micromolar range.

Genetic Insert: parM (K33A D63C T174A T175N D224C C287A)
Vector Backbone Description: Vector Backbone:pHis17; Vector Types:Bacterial Expression; Bacterial Resistance:Ampicillin
Defining Citation: PMID:20158267
Comments: The plasmid is used to express the plasmid segregation protein, ParM, from E. col. The protein is modified for use as the scaffold of an ADP biosensor, ATR-ParM. Two cysteine mutations are for label attachment (D63C and D224C); there is a mutation to inhibit filament formation (K33A), two mutations to weaken ATP binding (T174A and T175N), a mutation to change the exposed cysteine (C287A) and a C-terminal His6 tag to aid purification. When labelled with two iodoacetamidotetramethylrhodamine (IATR) fluorophores, this biosensor has a fluorescence intensity change of up to 20-fold and can be used to measure ADP in the range of hundreds of nanomolar to ~100 μM, in the presence of up to millimolar ATP. The biosensor can also be used for measurement of other nucleoside diphosphates e.g. GDP, UDP and others.
