Patterning protein complexes on DNA nanostructures using a GFP nanobody.
DNA nanostructures have become an important and powerful tool for studying protein function over the last 5 years. One of the challenges, though, has been the development of universal methods for patterning protein complexes on DNA nanostructures. Herein, we present a new approach for labeling DNA nanostructures by functionalizing them with a GFP nanobody. We demonstrate the ability to precisel...
متن کاملProtein Assembly Using the Staudinger Ligation
Introduction New methods are facilitating the total chemical synthesis of proteins. In particular, the chemical ligation of synthetic peptides provides a convergent route to proteins. Currently, the most common ligation method is “native chemical ligation” [1]. In native chemical ligation, the thiolate of an N-terminal cysteine residue of one peptide attacks the C-terminal thioester of a second...
متن کاملStreamlined Expressed Protein Ligation Using Split Inteins
Chemically modified proteins are invaluable tools for studying the molecular details of biological processes, and they also hold great potential as new therapeutic agents. Several methods have been developed for the site-specific modification of proteins, one of the most widely used being expressed protein ligation (EPL) in which a recombinant α-thioester is ligated to an N-terminal Cys-contain...
متن کاملProtein Ligation in Living Cells Using Sortase
Sortagging is a versatile method for site-specific modification of proteins as applied to a variety of in vitro reactions. Here, we explore possibilities of adapting the sortase method for use in living cells. For intracellular sortagging, we employ the Ca²⁺-independent sortase A transpeptidase (SrtA) from Streptococcus pyogenes. Substrate proteins were equipped with the C-terminal sortase-reco...
متن کاملScaffolded multiple cyclic peptide libraries for protein mimics by native chemical ligation.
The accessibility to collections, libraries and arrays of cyclic peptides is increasingly important since cyclic peptides may provide better mimics of the loop-like structures ubiquitously present in and - especially - on the surface of proteins. The next important step is the preparation of libraries of ensembles of scaffolded cyclic peptides, which upon screening may lead to promising protein...
