ENZYME entry: EC 4.6.1.15

Accepted Name
FAD-AMP lyase (cyclizing)
Alternative Name(s)
FMN cyclase
Reaction catalysed
FAD <=> AMP + H(+) + riboflavin cyclic-4',5'-phosphate
Comment(s)
  • While FAD was the best substrate tested the enzyme also splits ribonucleoside diphosphate-X compounds in which X is an acyclic or cyclic monosaccharide or derivative bearing an X-OH group that is able to attack internally the proximal phosphorus with the geometry necessary to form a P=X product; either a five-atom monocyclic phosphodiester or a cis-bicyclic phosphodiester-pyranose fusion.
  • The reaction is strongly inhibited by ADP or ATP but is unaffected by the presence of the product, cFMN.
