Nameriboflavin, FAD and FMN from GTP and ribulose-5-P
TypePATHWAY
DescriptionFlavin-adenine dinucleotide (FAD) is synthesized via flavinmononucleotide (FMN) and riboflavin (vitamin B2) from GTP, ribulose-5-phosphate and ATP in a 9-step pathway. FAD and FMN are important carriers of hydrogen and electrons which are usually found tightly bound or covalently linked to enzymes such as dehydrogenases, oxidases and monooxygenases. The pathway in bacteria and archaea/fungi vary slightly with the order in which a pair of reductase and deaminase steps take place.
