Better drugs, improved industrial applications and even cleaner laundry may be possible with a new computer method to predict which hybrid enzymes are likely to have high activity, according to a team of Penn State chemists and chemical engineers.
"FamClash is quite successful at qualitatively predicting the pattern of the specific activity of the hybrids," the researchers report in this weeks online issue of the Proceedings of the National Academy of Sciences. "By identifying incompatible residue pairs in the hybrids, this method provides valuable insights for protein engineering interventions to remedy these clashes," the researchers say. FamClash is a computer method used to predict which hybrid enzymes are likely to have activity and which are not. Hybrid enzymes form when researchers combine similar enzymes from two or more different organisms. The variant enzymes are broken and recombined with parts from the original enzymes creating the new one.
"We have worked out ways to make libraries of novel enzymes by splicing proteins together," says Alexander R. Horswill, postdoctoral fellow in chemistry. "We wanted to know how active the new enzymes would be compared to the wild type."

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
