University of Missouri researchers visualize "terminals" inside proline degrading enzyme

If subway terminals didn't exist and people had to exit subway stations to switch subway lines, transit time would increase. People also may encounter distractions, such as grabbing a cup of coffee, instead of getting on the other line. Molecules also use "terminals" to save transit time during enzyme-catalyzed processes. Using advanced X-radiation techniques, University of Missouri researchers were able to visualize one of these terminals inside of an enzyme that degrades proline, which is an amino acid that has a central role in metabolism.

Chemists adopt new approach to optimise enzyme for practical applications

Engineers are unlikely to tinker with the cooling system if they want to increase the size of an engine. Yet chemists at the Max Planck Institute for Coal Research have adopted an approach similar to this in their efforts to optimise an enzyme for practical applications. They

Proline repeats make teeth strong and resilient

A simple amino acid that is repeated in the center of proteins found in tooth enamel makes teeth stronger and more resilient, according to new research at the University of Illinois at Chicago.

Study: Gene therapy can reduce symptoms of Huntington's disease

Researchers at the California Institute of Technology (Caltech) have shown that a highly specific intrabody (an antibody fragment that works against a target inside a cell) is capable of stalling the development of Huntington's disease in a variety of mouse models.

Increasing the half life of proteins to treat diseases such as hepatitis B

Many biopharmaceuticals comprise small proteins that are quickly eliminated from the body. Scientists at the Technische Universitaet Muenchen (TUM) combine such small proteins with a kind of molecular balloon that swells and thus prolongs the half-life of the proteins in the body. The TUM spin-off XL-Protein GmbH has now started to further develop this new technology with blockbuster potential.

Study provides insights into genes that help maintain youthfulness of the skin

In the new print issue of Nature Genetics, scientists in Singapore and Germany report that mutations in the PYCR1 gene cause the rare genetic condition that results in premature skin aging and that is known as "wrinkly skin syndrome."

Scientists first evidence of cell-to-cell communication by amino acids

A team of researchers from the Massachusetts General Hospital Center for Engineering in Medicine (MGH-CEM) has found the first evidence of cell-to-cell communication by amino acids, the building blocks of proteins, rather than by known protein signaling agents such as growth factors or cytokines.

Discovery of second genetic risk factor for developing late-onset Alzheimer's disease

Researchers have discovered the second, strong genetic risk factor for developing late-onset Alzheimer's disease, according to a new report in the June 27th issue of the journal Cell, a Cell Press publication.

Model of proline dehydrogenase created

Researchers at the University of Missouri-Columbia recently created a model of proline dehydrogenase, an important cancer-preventing enzyme in the human body, and analyzed how it works.

New insights into how cells repair damaged DNA

Cancer researchers have discovered that a recently identified protein critical for repairing damaged genes uses an unusual mechanism to keep its repairs accurate.

Disruption of normal gene interaction linked to schizophrenia

Disruption of the normal interaction between the genes PRODH and COMT contributes directly to major symptoms of schizophrenia by upsetting the balance of the brain chemicals glutamate and dopamine, according to a group of investigators that includes a scientist now at St. Jude Children's Research Hospital.

Protein sequenced from 75,000 year old Iraqi

An international team led by researchers at the Department of Human Evolution, Max Planck Institute for Evolutionary Anthropology in Liepzig, Germany and Washington University in St. Louis, has extracted and sequenced protein from a Neanderthal from Shanidar Cave, Iraq dating to approximately 75,000 years old.

Researchers make millions upon millions of drug-like peptides quickly and efficiently

Two Johns Hopkins scientists have figured out a simple way to make millions upon millions of drug-like peptides quickly and efficiently, overcoming a major hurdle to creating and screening huge "libraries" of these super-short proteins for use in drug development.
