General annotation (Comments)

Function	Converts 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate into isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP) By similarity. HAMAP MF_00191
Catalytic activity	Isopentenyl diphosphate + NAD(P)+ + H2O = (E)-4-hydroxy-3-methylbut-2-en-1-yl diphosphate + NAD(P)H. HAMAP MF_00191 Dimethylallyl diphosphate + NAD(P)+ + H2O = (E)-4-hydroxy-3-methylbut-2-en-1-yl diphosphate + NAD(P)H. HAMAP MF_00191
Cofactor	Binds 1 3Fe-4S cluster By similarity. HAMAP MF_00191
Pathway	Isoprenoid biosynthesis; dimethylallyl diphosphate biosynthesis; dimethylallyl diphosphate from (2E)-4-hydroxy-3-methylbutenyl diphosphate: step 1/1. HAMAP MF_00191 Isoprenoid biosynthesis; isopentenyl diphosphate biosynthesis via DXP pathway; isopentenyl diphosphate from 1-deoxy-D-xylulose 5-phosphate: step 6/6. HAMAP MF_00191
Sequence similarities	Belongs to the IspH family.
