Middle school students co-author research on enzyme for activating promising disease-fighters

29.07.2010
Grown-ups aren't the only ones making exciting scientific discoveries these days. Two middle school students from Wisconsin joined a team of scientists who are reporting the first glimpse of the innermost structure of a key bacterial enzyme.

It helps activate certain antibiotics and anti-cancer agents so that those substances do their job. Their study appears in ACS' weekly journal Biochemistry. The student co-authors of the study are from Edgewood Campus Middle School in Madison and participated in Project CRYSTAL, a special program that provides middle school students with hands-on laboratory experience.

In the report, study leader Hazel Holden and colleagues note intense scientific interest in a chemical process called methylation, which increases the activity of DNA, proteins, and other substances in the body by transferring methyl (CH3) groups to them. Special enzymes called methyltransferases make methylation possible, and these proteins are very important in a myriad of key biological processes.

Holden and colleagues studied a bacterial methyltransferase involved in the production of tetronitrose, a component of the promising anti-cancer agent, tetrocarcin, and the antibiotic kijanimicin. The methyltransferase seems to play a key role in activating these disease-fighters. The scientists identified the 3D structure of this methyltransferase, a key step in determining how it works and how it might be modified for potential use in medicine.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
