ChemikerInnen entdecken unbekannte Eigenschaften eines Enzyms, das in der Natur an der Synthese von Blattgrün beteiligt ist

Wenn Pflanzen Licht, Wasser und Kohlendioxid in energiereiche, organische Stoffe wie Glucose und Sauerstoff umwandeln, benötigen sie dafür den grünen Blattfarbstoff, das Chlorophyll. Nur dieser kann die für die Photosynthese so wichtigen Sonnenstrahlen aufnehmen. Für die Produktion von Chlorophyll brauchen Pflanzen wiederum bestimmte Enzyme, eines davon interagiert auch mit Licht.

Dieses haben sich Chemiker und ChemikerInnen der Universität Graz näher angeschaut und sind dabei auf bislang unbekannte Eigenschaften dieses Enzyms gestoßen, je nachdem von welcher Pflanze sie stammen. „Konkret geht es um das Koenzym NADPH, das an sehr vielen Stoffwechselprozessen der Zelle beteiligt ist. Bis jetzt war nur bekannt, dass diese speziellen Enzyme NADPH akzeptieren. Wir haben herausgefunden, dass in gewissen Organismen auch solche Enzyme existieren, die das verwandte Koenzym NADH verwenden können“, erklärt Wolfgang Kroutil vom Institut für Chemie der Universität Graz. Die Ergebnisse geben Einblick in die Grundlagen der Erkennung von Koenzymen in Proteinen und könnten die Basis für Anwendungen in neuen Synthesen sein.

Die Ergebnisse haben die ForscherInnen in der aktuellen Ausgabe des Katalyse-Fachjournals „ChemCatChem“ publiziert. Zudem sind sie auch gestalterisch kreativ geworden: Das aktuelle Cover stammt von Verena Resch, ehemalige Dissertantin von Kroutil und Gründerin des Luminous Lab, das sich auf die ansprechende Visualisierung von Forschungsergebnissen spezialisiert hat.

Fair distribution: Researchers determine just greenhouse gas budgets for all EU regions

Ten years ago, on 12 December 2015, the Paris Climate Agreement was signed at the UN Climate Conference. In order to limit global warming to well below two degrees, only a certain amount of CO2 may be emitted worldwide. While the focus was originally on national emission targets, more than 200 subnational regions and almost 300 cities have now adopted their own targets. But how many emissions are they fairly entitled to? Researchers at the University of Graz have now developed transparent criteria for fair distribution at the subnational level for the first time and determined corresponding greenhouse gas budgets for all European regions. The paper was published today in the scientific journal Nature Communications.

Chemical Christmas show at the University of Graz: An explosive evening at the Schauspielh

At the beginning of December, the University of Graz transformed the theater into a laboratory: as part of “Chemical Life,” teacher training students staged a chemical Christmas show for Styrian school classes—complete with ethanol rockets, nitrogen snow, and glowing effects. An evening designed to inspire interest in studying chemistry.

Train by train: Koralm railway accelerates exchange between the Universities

Lectures at the University of Klagenfurt in the morning, seminars at the University of Graz in the afternoon: Austria's longest tunnel and a journey time of around 45 minutes make it easy. The Koralm railway increases the speed of networking between the two university locations. The collaboration builds on existing cooperation - for example in the areas of teacher training, Slavic studies and as employers, the universities are well coordinated.
