Enzymes help with specific functions that are vital to the operation and overall health of the human body. They help speed up chemical reactions and are essential for respiration, digestion, muscle ...

Life has evolved over billions of years, adapting to the changing environment. Similarly, enzymes—proteins that speed up biochemical reactions (catalysis) in cells—have adapted to the habitats of ...

(Nanowerk News) Enzymes are the molecule factories in biological cells. However, which basic molecular building blocks they use to assemble target molecules is often unknown and difficult to measure.

The function of the glycolytic enzyme hexokinase 1 differs depending on its location within the cell, according to a Northwestern Medicine study published in Molecular Cell. The enzyme uses different ...

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

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 ...

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. The researchers said the AI tool, ...
