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 ...

Two-step nanocage: Individual enzymes (orange and green) are first attached to half-cage structures. Half cages are then assembled into full cages, where reactants are brought into close proximity.

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 ...

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: ...

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

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.

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

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, ...
