IntEnz Enzyme Nomenclature
EC 5.3.3.2

Names

Accepted name:
isopentenyl-diphosphate Δ-isomerase
Other names:
isopentenylpyrophosphate Δ-isomerase
isopentenylpyrophosphate isomerase
methylbutenylpyrophosphate isomerase
IPP isomerase
Systematic name:
isopentenyl-diphosphate Δ32-isomerase

Reaction

Cofactors

Comments:

The enzyme from Streptomyces sp. strain CL190 requires FMN and NAD(P)H as cofactors. Activity is reduced if FMN is replaced by FAD, but the enzyme becomes inactive when NAD(P)H is replaced by NAD+ or NADP+. That enzyme also requires Mg2+, Mn2+ or Ca2+ for activity.
