Engineered solubility tag for solution NMR of proteins
Engineered solubility tag for solution NMR of proteins
Abstract
The low solubility of many proteins hinders large scale expression and purification as well as biophysical measurements. Here, we devised a general strategy to solubilize a protein by conjugating it at a solvent-exposed position to a 6 kDa protein that was re-engineered to be highly soluble. We applied this method to the CARD domain of Apoptosis-associated speck-like protein containing a CARD (ASC), which represents one member of a class of proteins that are notoriously prone to aggregation. Attachment of the tag to a...

Segmental isotope labeling of proteins for NMR structural study using a protein S tag for higher expression and solubility
Segmental isotope labeling of proteins for NMR structural study using a protein S tag for higher expression and solubility
Abstract A common obstacle to NMR studies of proteins is sample preparation. In many cases, proteins targeted for NMR studies are poorly expressed and/or expressed in insoluble forms. Here, we describe a novel approach to overcome these problems. In the protein S tag-intein (PSTI) technology, two tandem 92-residue N-terminal domains of protein S (PrS2) from Myxococcus xanthus is fused at the N-terminal end of a protein to enhance its expression and solubility. Using...

Overcoming the solubility limit with solubility-enhancement tags: successful applications in biomolecular NMR studies
Overcoming the solubility limit with solubility-enhancement tags: successful applications in biomolecular NMR studies
Abstract Although the rapid progress of NMR technology has significantly expanded the range of NMR-trackable systems, preparation of NMR-suitable samples that are highly soluble and stable remains a bottleneck for studies of many biological systems. The application of solubility-enhancement tags (SETs) has been highly effective in overcoming solubility and sample stability issues and has enabled structural studies of important biological systems previously deemed...

Authors: Howe PW
Maximising solubility is a key step in applying solution-state NMR to proteins. The 'microbatch' crystallisation screening method can be adapted to screen for protein solubility. In this approach, drops of test solutions are placed under paraffin oil in 96-well screening plates. This requires very small amounts of protein, is easy to set up...
