Researchers devised a reversibly lockable DNA device for enclosing an enzyme and controlling its access to substrates. Turning on and off the activity of a single enzyme on demand is a much desired ...

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

The immune system must maintain a delicate balance to defend against harmful threats while avoiding excessive inflammation.

By resurrecting a 3.2-billion-year-old enzyme and studying it inside living microbes, researchers at the University of ...

While the process of copying DNA to make new strands includes a proofreading function to ensure accuracy, the so-called reverse transcriptase enzymes that make RNA into DNA copies perform no such ...

The Michaelis-Menten equation is used to describe the dynamics of an enzymatic reaction, in which an enzyme interacts with a substrate to generate some product before the enzyme is released. Cells are ...

Enzymes are the molecular machines that power life; they build and break down molecules, copy DNA, digest food, and drive virtually every chemical reaction in our cells. For decades, scientists have ...

Gibberellic acid (GA) enhances the synthesis of α-amylase and ribonuclease in isolated aleurone layers and this process is inhibited by abscisin. Removal of gibberellic acid in mid-course of α-amylase ...

In the early 20th century, humans discovered vitamins, and then trace elements and minerals. It was only in the mid-1980s that humans realized the importance of enzymes. Nobel Prize in Physiology and ...

Molecular biology has transitioned to a new era where precise genetic manipulation plays a critical role in research, medicine, and biotechnology. Among the vital tools in this field are cloning ...

This is a preview. Log in through your library . Abstract The activity of crude preparations of the indoleacetic acid oxidase of etiolated peas is increased by light. The light receptor is believed to ...
