C-di-GMP regulates important processes involved in biofilm formation and virulence factors production in several bacteria. Herein we report a simple fluorescent strategy that allows for the detection of c-di-GMP (as low as 320 nM) using a Vc2 class I riboswitch domain as the sensing region and spinach as the fluorescent reporting module.
