This release is available in French. Scientists at the Institute for Research in Immunology and Cancer (IRIC) of the Université de Montréal have discovered a key mechanism used by cells to efficiently ...

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 ...

FOR a long time two viewpoints regarding the mechanism of enzymatic activity have profoundly influenced our conceptions in this field. To Oscar Loew is due the credit for the original suggestion that ...

The function of an enzyme, critical to most forms of life, has been revealed. A research team, led by the John Innes Centre found that the enzyme DNA topoisomerase VI (topo VI) performs a critical ...

A new study led by scientists at IUPUI and Indiana University Bloomington is the first to describe a biochemical mechanism that increases the activity of a molecule whose presence is observed in many ...

Researchers from Tokyo Metropolitan University have developed a new structure determination method using nuclear magnetic ...

Researchers discovered the 3D structure and mode of action of DGAT1, the enzyme that synthesizes triglycerides. Doctors regularly warn their patients that having high levels of triglycerides, a major ...

Bacterial styrene oxidase isomerase has been known to science for more than three decades, but its mechanism of action has ...

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 human body, proteins called enzymes help speed up chemical reactions that are vital for life. After you eat, enzymes help your body break down food and obtain energy. Enzymes are also ...

A harmful and often deadly substance made by bacteria, a bacterial toxin manipulates host cell functions and disrupts vital cell processes in a living organism. Bacterial toxins hit host organisms ...
