Study reveals that reversible chemical modifications can inhibit pyruvate kinase and affect its variants differently, ...

It is now possible to obtain three-dimensional, high-resolution images of enzyme activity in tissue samples or whole organs -- thanks to probe molecules that anchor fluorescent dyes within tissue as ...

Enzymes originally evolved in high-temperature environments and later adapted to lower temperatures as Earth cooled. Scientists discovered that a key shift in enzyme function occurred over ...

Enzymes evolved to efficiently operate in low-temperature environments via key substitutions of amino acids in their active site, which lowers the activation energy of catalytic reactions. Life has ...
