Enzyme reactions

• Enzyme class: E.C.5.3.3.2 - isopentenyl-diphosphate Delta-isomerase.
• Pathway: Terpenoid biosynthesis
• Reaction: isopentenyl diphosphate = dimethylallyl diphosphate

isopentenyl diphosphate (Bound ligand (Het Group name = IPE) corresponds exactly) = dimethylallyl diphosphate

• Cofactor: FMN or FAD; Mn(2+) or Mg(2+) or Ca(2+)

FMN (Bound ligand (Het Group name = FNR) corresponds exactly) or FAD Mn(2+) or Mg(2+) or Ca(2+)
