WITH our present knowledge of enzyme processes any conception of their mechanism must be essentially highly speculative. In the work under notice the author makes no claim to deal comprehensively with ...

Enzymes that cut DNA at specific sites are called endonucleases; these enzymes play many roles in genomic replication, fidelity, and defense. The initial discovery of restriction endonucleases in the ...

Sir2, an enzyme belonging to sirtuins, has been shown to be involved in the deacetylation of proteins. Researchers from the Institute of Science Tokyo reveal that a tandem allosteric effect of ...

Sir2, an enzyme belonging to sirtuins, has been effectively involved in the deacetylation of proteins. A tandem allosteric effect of reactant and product is responsible for the efficient deacetylation ...

Enzymes are the molecular machines that power life; they build and break down molecules, copy DNA, digest food, and drive ...

Advanced microscopy techniques give scientists valuable clues for how to fight an enzyme that is leading to a rise in cases of antibiotic-resistant bacterial infections worldwide. Bacteria draw from ...
