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 ...

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, ...

A new artificial intelligence tool can predict the functions of enzymes based on their amino acid sequences, even when the enzymes are unstudied or poorly understood. Researchers said the AI tool, ...

Scientists used x-rays to decipher the three-dimensional structure of the main protease of the virus that causes COVID-19 at different temperatures. The background image shows the full structure at ...

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 ...

RIKEN researchers have discovered how an enzyme modifies gene expression by targeting certain stretches of messenger RNA ...

Scientists discovered hundreds of energy-making enzymes secretly working on human DNA—revealing a hidden “mini-metabolism” ...

Inosine is a nucleoside that occurs naturally in transfer RNAs (tRNAs) and is essential for proper RNA translation. It is commonly found at the wobble position of anticodons, allowing for greater ...

Deep in your muscles, an enzyme called AMPD1 helps turn chemical fuel into usable energy. When it does not work well, muscles tire faster.
