Scientists at the University of Leicester have shown that the textbook explanation of how enzymes work is wrong - at least for some enzymes.
Their discovery may explain why attempts to make artificial enzymes have often been disappointing. Industry must now re-think the rationale for the design of biological catalysts and its approaches to drug design. Enzymes are biological molecules that accelerate chemical reactions and are central to the existence of life. The new breakthrough that could revolutionise the application of enzymes in human well-being has been made at the University of Leicester.
Professors Nigel Scrutton and Michael Sutcliffe, of the Department of Biochemistry, have discovered a new phenomenon occurring at the atomic level that dictates how enzymes work. Their study of enzymes - which are vital for catalysis within industry - reveals that chemical reactions can proceed through energy barriers. This is contrary to received wisdom on how enzyme reactions work.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
