A rapid, easy-to-use DNA amplification method at 37 Celcius

Scientists in Japan have developed a way of amplifying DNA on a scale suitable for use in the emerging fields of DNA-based computing and molecular robotics. By enabling highly sensitive nucleic acid detection, their method ...

Steroid binding to metabolic enzyme

The human cytochrome P450 enzymes are responsible for metabolizing a variety of substances—from lipids (fats) and steroid hormones to drugs and toxic chemicals.

The start of a new era in stem cell therapy

A recent study published in the April 8 issue of Nature Chemical Biology improves on the "Cellular Reprogramming" method developed by Nobel Laureate in Medicine and Physiology Prof. Shinya Yamanaka, making it possible to ...

Researchers identify the source of asymmetry in RNA-DNA hybrids

A study headed by the Institute for Research in Biomedicine (IRB Barcelona) and published in the journal CHEM furthers the understanding of the asymmetry between nucleic acid hybrids. This advance may make a significant contribution ...

Construction kit for custom-designed products

Microorganisms often assemble natural products similar to product assembly lines. Certain enzymes, non-ribosomal peptide synthetases (NRPS), play a key role in this process. Biotechnologists at Goethe University have now ...

Lab-grown dairy: The next food frontier

Lab-grown meat is getting a lot of attention along with plant-based meat substitutes. Technology is driving the industry toward providing alternatives to conventionally produced food products. Dairy proteins may be the next ...

A homing beacon for chemotherapy drugs

Killing tumor cells while sparing their normal counterparts is a central challenge of cancer chemotherapy. If scientists could put a "homing beacon" in tumors, they could attract these medicines and reduce side effects caused ...

New family on the block: A novel group of glycosidic enzymes

A group of researchers from Japan has discovered a novel enzyme from a soil fungus. In their study published in the Journal of Biological Chemistry, they speculate that this enzyme plays important roles in the soil ecosystem, ...

Learning from nature's bounty: New libraries for drug discovery

Natural products, or their close derivatives, make some of our most potent medicines, among which macrocycles with their large carbon-rich ring systems are one class. The size and complexity of macrocycles has made it difficult ...

Researchers synthesize healing compounds in scorpion venom

A scorpion native to Eastern Mexico may have more than just toxin in its sting. Researchers at Stanford University and in Mexico have found that the venom also contains two color-changing compounds that could help fight bacterial ...

Potassium hunting on protein factories

Groundbreaking research at the new long-wavelength macromolecular crystallography beamline (I23) at Diamond Light Source has for the first time demonstrated the location of potassium ions in bacterial ribosomes. Ribosomes ...

Scientists uncover binding secret behind protein 'superglue'

Scientists from Nanyang Technological University, Singapore (NTU Singapore) have pinpointed how a special class of plant-derived enzymes, known as peptide ligases, work to join proteins together. Such binding is an important ...

Citizen scientists design brand new proteins

A team of researchers encoded their specialized knowledge into the computer game Foldit to enable citizen scientists to successfully design synthetic proteins for the first time.
