Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists ...

A metabolic enzyme found in the support cells surrounding tumors may hold the key to predicting which cancer patients will ...

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 ...

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 ...

The field of microbial enzyme research is rapidly evolving as biotechnology and industrial processes increasingly depend on the exploitation of microbial ...

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 required to make new ...

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

Researchers discovered a kinase-driven phosphorylation switch that activates DNA packaging machinery, aligning nucleosomes at ...

Within each cell, the power houses called mitochondria continuously break down molecules derived from food to generate energy as well as to produce new molecules that serve as building blocks of cells ...
