Efficient formation of water- and air-stable aza-ylides has been achieved using the Staudinger reaction between electron-deficient aromatic azides such as 2,6-dichlorophenyl azide and triarylphosphines. The reaction proceeds rapidly and has been successfully applied to chemical modification of proteins in living cells.

A mutant hydrolase optionally fused to a protein of interest is provided. The mutant hydrolase is capable of forming a bond with a substrate for the corresponding nonmutant (wild-type) hydrolase which is more stable than the bond formed between the wild-type hydrolase and the substrate. Substrates for hydrolases comprising one or more functional groups are also provided, as well as methods of using the mutant hydrolase and the substrates of the invention. Also provided is a fusion protein capable of forming a stable bond with a substrate and cells which express the fusion protein.
incorporated with a cycloalkyne moiety, from the corresponding azides is developed. Treatment of diynes bearing strained and terminal alkyne moieties with a copper salt enabled terminal alkyne-selective clickconjugation with azides, whereas a more azidophilic strained alkyne moiety was transiently protected from the clickreaction via complexation with copper.

The invention aims in establishing a method for modifying biomolecules using a reaction that efficiently modifies biomolecules and is widely applicable. The invention thus provides a cyclic compound containing two triazole rings formed by adding and ligating an azide compound possessing an azido group to each of the two carbon-carbon triple bond sites of an eight-membered cyclic skeleton of a cyclic diyne compound by a double click reaction; a method for producing a cyclic compound using a double click reaction; and a method for modifying biomolecules.
