... 2005) doi:10.1111/j.1742-4658.2005.04931.x Coenzyme F 420 is a 5-deazaflavin. Upon reduction, 1,5 dihydro -coenzyme F 420 is formed with a prochiral centre at C5. All the coenzyme F 420 -dependent enzymes ... when irradiated with UVA light. The fluorescence is due to coenzyme F 420 , a 7,8-didemethyl-8-hydroxy-5-deaza- riboflavin derivative (Fig. 1). The coenzyme, which is generally pres...
