Production of mutant streptavidin protein and investigation of its effect on the performance of streptavidin [PDF]
Objective(s): Streptavidin is a versatile protein in cell science. The tetramer structure of streptavidin plays a key role in this binding, but this form interferes with some assays.

Structure and substrate selectivity of the 750-kDa α6β6 holoenzyme of geranyl-CoA carboxylase. [PDF]
Geranyl-CoA carboxylase (GCC) is essential for the growth of Pseudomonas organisms with geranic acid as the sole carbon source. GCC has the same domain organization and shares strong sequence conservation with the related biotin-dependent carboxylases 3 ...

An improved method for surface immobilisation of RNA: application to small Non-Coding RNA - mRNA pairing [PDF]
Characterisation of RNA and its intermolecular interactions is increasing in importance as the inventory of known RNA functions continues to expand. RNA-RNA interactions are central to post-transcriptional gene regulation mechanisms in bacteria, and the ...

Protein-mediated dethreading of a biotin-functionalised pseudorotaxane [PDF]
In this article, we describe the synthesis of new biotin-functionalised naphthalene derivatives 3 and 4 and their complexation behaviour with avidin and neutravidin using a range of analytical techniques.
