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 ...

Specific glycans attached to the GnT-IVa and GnT-IVb can bind to the enzyme’s ligand-binding site, interfering with recognition and binding to the glycosylation proteins’ normal glycoprotein ...

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 ...
