spycather

In the last few years, hydrogens made from natural or synthetic polymers have been investigated due to their extensive application in clinical medicine and synthetic biology. Compared to traditional biological material, protein-based multifunctional biological material is low-cost, facile and eco-friendly. However, strategies for assembling 3D molecular networks synthesized only by protein molecular remain underdeveloped. The reason why investigating this technology is still tough is lack of protein-based cross linking agents. Inspired by the self-catalysis of isopeptide bond between Lys and Asp in Streptococcus pyogenes fibronectin-binding protein FbaB, researchers split the catalytic domain and obtained two peptide called SpyTag(the short one) and SpyCatcher(the long one) which are able to form isopeptide bond with the other without any assistant. By fusing SpyTag and SpyCatcher with functional domains respectively, researchers solved the problem tactfully.
