CHANGES of volume accompanying enzyme hydrolysis have been utilised by Sreenivasaya and Sastry 1 to follow the kinetics of enzyme action by means of the dilatometer. The procedure employed in the ...

The enzyme accelerates this reaction by 10 17 times, simply by positioning negative and positive charges in the active centre. Since the substrate contains a negatively charged group that is split off ...

Real-time measurement of the initial stage of an enzyme–substrate reaction is essential for reproducible enzyme kinetics data. Automated direct-flow injection systems couple with various detection and ...

Researchers have captured a bacterial enzyme in the act of encircling collagen and pulling a single strand through its ...

Microtubules, the dynamic filaments that form the cell's internal scaffolding, have long been viewed as mere passive ...

Enzymes are biological catalysts that speed up chemical reactions in living organisms. They are essential for life, as they play a crucial role in various biological processes, such as digestion, ...

Chemists at MIT have introduced an engineered biosynthetic enzyme that accepts a wider range of substrates into periwinkle plant culture to make unnatural analogs of alkaloids (Nat. Chem. Biol., DOI: ...

Pericyclic reactions, in which electrons move in concert to rearrange a molecule’s structure, are standard tools for synthetic chemists. But examples of such transformations in nature are fairly rare.

Collagen is an important protein that helps build the tissues of humans and animals. It is very strong because it is made of ...

The Tang, Garg, and Houk research groups have discovered nature's natural protein catalysts (enzymes) that catalyze the Alder-ene reaction. All groups are part of the UCLA Department of Chemistry & ...

Scientists from the University of Portsmouth and the University of Manchester say they have developed a fusion enzyme that can help break down polyester fibers in blended textiles, a category of waste ...
