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 ...

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 ...

Imagine trying to bake a cake without heat. You’ve got all the ingredients like flour, eggs and sugar, but nothing is happening. That’s what your body would be like without enzymes: potential but no ...

The structure of enzymes determines how they control vital processes such as digestion or immune response. This is because the protein compounds are not rigid, but can change their shape through ...

"This structure answers a long-standing question for how two essential regions, N-lip and C-lip, which are located on opposite ends of this protein in humans, come together to form a function enzyme ...

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 ...

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 ...

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, ...
