Scientists from the Université de Montréal and McGill University have re-engineered a human enzyme, a protein that accelerates chemical reactions within the human body, to become highly resistant to ...

Enzymes, nature's molecular architects, have been at the heart of industrial processes for decades. Today, the dynamic field of Enzyme Engineering and Modification is driving these biocatalysts ...

Sanofi has developed a simpler way to create site-specific antibody-to-mannose-6-phosphate (M6P) conjugates that eliminates the need for enzyme remodeling. This more straightforward method makes M6P ...

A consortium of scientists has discovered new non-histone targets for one enzyme previously believed to modify only histones -- the group of proteins that creates tightly bundled packages of DNA ...

We have synthesized a hybrid subtilisin the solubility of which can be regulated by photoirradiation through coupling with a photoresponsive copolymer that carries spiropyran groups in its side chains ...

This method uses polymer modifications to tune enzyme activity for increased solubility in non-native solvents. Tuning the miscibility of enzymes in non-native solvent environments has important ...

One of these days, the ability of our cells and tissues to regenerate and repair themselves will come to a stop. Researchers hoping to better understand the processes that regulate aging are studying ...

A seemingly subtle swap of metals—substituting a zinc ion with a cobalt ion—and a mutation ramps up the overall electric field strength at the active site of an enzyme, Stanford scientists find. The ...

Cellular RNAs are chemically modified by many RNA modification enzymes; however, often the functions of modifications remain unclear, such as for pseudouridine formation in the tRNA TΨC arm by the ...

Covalent attachment of ubiquitin and SUMO to proteins plays a major role in regulating cellular functions. Both modifications depend on a similar enzymatic cascade. Ubiquitination involves a single E1 ...

Paracatalytic enzyme modifications result from the oxidation of enzyme-substrate carbanions by extrinsic oxidants. During the oxidation of enzyme-activated substrates, transiently reactive ...
