The enzyme transhydrogenase plays a central role in regulating metabolic processes in animals and humans alike. Malfunction can lead to serious disorders. For the first time, structural biologists ...

A central question in molecular biology is how cells protect their chromosomes from damage during repeated cell division. At ...

Researchers have used cryo- electron microscopy to elucidate for the first time the structure and function of a very small enzyme embedded in cell membranes. This enzyme builds complex sugar trees ...

SANTA CRUZ, CA -- Researchers at the University of California, Santa Cruz, have determined the three-dimensional structure of an RNA enzyme, or "ribozyme," that carries out a fundamental reaction ...

Antibiotics revolutionized health care when they were introduced in the early twentieth century, making many severe and often ...

Researchers from Tokyo Metropolitan University have developed a new structure determination method using Nuclear Magnetic Resonance (NMR) spectroscopy which shows how different parts of complex ...

While most enzymatic activity is conducted through chemical binding interactions between molecules, in some cases, the mere presence of an enzyme can affect intracellular functions. While exploring ...

A new method has enabled the natural structure of particularly large and complex enzymes to be revealed. Scientists have investigated a multi-enzyme complex that plays an essential role in metabolism ...

Molecular structure of the papainlike enzyme known as PLPro. This enzyme allows the viruses that cause SARS, MERS, and COVID-19 to infect cells and replicate and suppress the host's immune function.
