RESUMEN
We have synthesized a light-activatable ("caged") derivative of glucosamine-6-phosphate (GlcN6P), which only upon irradiation becomes a cofactor for the glmS riboswitch. This glmS riboswitch maintains its activity when embedded in the 3'-untranslated region of eukaryotic mRNA molecules and caged GlcN6P reduces the amount of translated EGFP upon irradiation with light in vitro.
