EC 2.5.1.129     
Accepted name: flavin prenyltransferase
Reaction: dimethylallyl phosphate + FMNH2 = prenylated FMNH2 + phosphate

Glossary: prenylated FMNH2 = 3,3,4,5-tetramethyl-7-[(2S,3S,4R)-2,3,4-trihydroxy-5-(phosphonatooxy)pentyl]-2,3-dihydro-1H,7H-naphtho[1,8-fg]pteridine-9,11(8H,10H)-dione
Other name(s): ubiX (gene name); PAD1 (gene name)
Systematic name: dimethylallyl-phosphate:FMNH2 prenyltransferase
Comments: The enzyme produces the modified flavin cofactor prenylated FMNH2, which is required by EC 4.1.1.98, 4-hydroxy-3-polyprenylbenzoate decarboxylase, and EC 4.1.1.102, phenacrylate decarboxylase. The enzyme acts as a flavin prenyltransferase, linking a dimethylallyl moiety to the flavin N-5 and C-6 atoms and thus adding a fourth non-aromatic ring to the flavin isoalloxazine group.
