Enzymes are proteins that can change shape and therefore become active or inactive. An activator molecule (green pentagon) can bind to an enzyme (light green puzzle shape) and change its overall shape ...

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 ...

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, ...

Researchers defined the structure of a substrate-bound iron 2-oxoglutarate (Fe/2OG) enzyme to explore whether these enzymes could be used to create a wide array of molecules. They saw that Fe/2OG ...

It is well known in physics and chemistry that equal charges repel each other, while opposite charges attract. It was long assumed that this principle also applies when enzymes – the biological ...

A single enzyme that can generate all four nucleoside triphosphates, the building blocks of ribonucleic acid (RNA), has been ...

An analysis of an unusual enzyme could result in a new generation of antimicrobial medicines to counter antibiotic resistance ...

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: ...

Bionic enzymes got a needed boost in speed thanks to new research. By pairing a noble metal with a natural enzyme, scientists created a hybrid capable of churning out molecules at a rate comparable to ...

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 ...

Gifu University scientists have uncovered how a brain-specific enzyme reshapes protein-linked sugar chains to facilitate the ...
