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 ...

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 ...

Malathy Palayam, Aleczander Young, Lior Tal, and Nitzan Shabek at the UC Davis Department of Plant Biology are exploring the mechanism by which the plant hormone strigoractone regulates a massive ...

Researchers at the Department of Cell and Molecular Biology, Karolinska Institutet have captured the first detailed molecular snapshots of human polynucleotide phosphorylase (hPNPase) in action, ...

Gene editing is one of the latest breakthroughs in biology. The widely known CRISPR-Cas gene editing system provided prokaryotes (organisms that lack cell nuclei) an immunity against foreign DNA.

Researchers have determined the atom-by-atom structure of the fermentation enzyme phosphoketolase by cryogenic electron microscopy. They identified details that were mistakenly characterized by X-ray ...

For the first time, the structure of a DNA enzyme complex implicated in infertility and cancer has been obtained using cryo-electron microscopy (cryo-EM). A collaboration of researchers, led by ...

As sessile organisms, plants have to continually adapt their growth and architecture to the ever-changing environment. To do so, plants have evolved distinct molecular mechanisms to sense and respond ...
