UTP + riboflavin
UDP + FMN
activity with UTP is at least one order of magnitude less efficient

?
CTP + riboflavin
CDP + FMN
at reaction temperatures of up to 85°C (the temperature of the natural habitat of Methanocaldococcus jannaschii) riboflavin is completely converted to FMN

?
CTP + riboflavin
CDP + riboflavin 5'-phosphate
most active with CTP as the substrate
-
-
?
CTP + riboflavin
CDP + riboflavin 5'-phosphate
utilizes CTP rather than ATP as the donor nucleotide

enzyme-DNA binding analysis using the recombinant enzyme, overview. FMN-free pyRbkR protein binds two DNA fragments containing candidate regulatory sites upstream of the arfA and ribB genes in Pyrobaculum yellowstonensis. Both DNA fragments demonstrate specific interaction with pyRbkR, with apparent EC50 values in the range of 20-40 nM
