The engineered variant of Ф24B sequenced in this study, Ф24B::Cat [ 22], possesses a stx operon that has been replaced with the cat gene, which confers chloramphenicol resistance upon its lysogen.
However, we did decide to include the best of the engineered variants in lib1 in the expectation that they could potentially alter the FRET response of the biosensor.
The researchers engineered variants of N-WASP by combing two heterologous autoinhibitory input domains [PDZ and SH3 (Src homology 3)] with the output domain of N-WASP.
Specifically, using large ligands to acutely increase the size of engineered variants of the transferrin receptor, we demonstrate that an increase in the steric bulk of a receptor dramatically decreases its probability of uptake by clathrin-coated structures.
In the present study, far-UV CD spectroscopy and explicit-solvent MD simulations are used to investigate the structural stability of Top7 and the engineered variant under extreme conditions of temperature and pH.
Growing restrictions stemming from biosecurity concerns now affect research activity across a range of infectious diseases and have most recently been highlighted by concerns over the publication of research into the production of genetically engineered variants of the influenza A subtype H5N1 virus (36 ).
One of the engineered variants (WN-Fc), bound with high affinity to a wide range of solid tumor cell lines (e.g., colon, lung, prostate, skin, ovarian, and mammary tumors).
The engineered variants often have a high degree of similarity with the wild-type progenitor protein, necessitating a tool (e.g., antibody) to distinguish the wild-type and variant protein forms.
After 10 days of induction, the engineered variants upregulated myogenic markers in ADSCs and fibroblasts to a greater degree than WTMyoD.
Most of the inteins used in biotechnology are derived from prokaryotic organisms, or are engineered variants of the S. cerevisiae VMA1-intein.
This bacterium has become a molecular biology workhorse because it can be induced to produce large amounts of recombinant DNA molecules by inserting plasmids, the bacteriophage λ or genetically engineered variants of these agents into it.
