Comments |
The cofactors FMN and FAD participate in numerous processes in all organisms, including mitochondrial electron transport, photosynthesis, fatty-acid oxidation, and metabolism of vitamin B6, vitamin B12?and folates [5]. While monofunctional riboflavin kinase is found in eukaryotes, some bacteria have a bifunctional enzyme that exhibits both this activity and that of EC?2.7.7.2, FMN adenylyltransferase [5]. A divalent metal cation is required for activity (with different species preffering Mg2+, Mn2+?or Zn2+). In?Bacillus subtilis, ATP can be replaced by other phosphate donors but with decreasing enzyme activity in the order ATP > dATP > CTP > UTP [6]. |
