Category: Solubility enhancement tags (SETs)
Cleavage of the fusion proteins often re-introduces problems with solubility and stability. Here we describe the use of N-terminally fused protein G (B1 domain) as a non-cleavable solubility-enhancement tag (SET) for structure determination of a dimeric protein complex. The SET enhances the solubility and stability of the fusion product dramatically while not interacting directly with the protein of interest.
How do solubility fusion tags produce soluble proteins? Short fast 1 minute answer!
The ability of solubility fusion tags to produce soluble protein is only the first step in the pathway towards protein production. As many of these…
Does the H tag work as a solubility enhancer? Short fast 1 minute answer!
Regarding the H tag, it did not function as a solubility enhancer tag, but it improved the production levels of target proteins in E. colisimilarly…
Do small peptide tags stimulate solubility in proteins? Short fast 1 minute answer!
Small peptide tags called SET tags, which feature highly acidic amino acid sequences, have also been shown to stimulate solubility in a few partner proteins.
How can I incorporate solubility enhancers into my fusion tag design? Short fast 1 minute answer!
Fusion tags can be incorporated using different strategies: affinity and solubility tags are set individually or together, and sites for protease cleavage are designed between…
