General annotation (Comments)
| Function | Converts 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate into isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP). HAMAP-Rule MF_00191 |
| Catalytic activity | Isopentenyl diphosphate + NAD(P)+ + H2O = (E)-4-hydroxy-3-methylbut-2-en-1-yl diphosphate + NAD(P)H. HAMAP-Rule MF_00191 Dimethylallyl diphosphate + NAD(P)+ + H2O = (E)-4-hydroxy-3-methylbut-2-en-1-yl diphosphate + NAD(P)H. HAMAP-Rule MF_00191 |
| Cofactor | Binds 1 3Fe-4S cluster per subunit By similarity. |
| Pathway | Isoprenoid biosynthesis; dimethylallyl diphosphate biosynthesis; dimethylallyl diphosphate from (2E)-4-hydroxy-3-methylbutenyl diphosphate: step 1/1. Ref.4 Isoprenoid biosynthesis; isopentenyl diphosphate biosynthesis via DXP pathway; isopentenyl diphosphate from 1-deoxy-D-xylulose 5-phosphate: step 6/6. Ref.4 |
| Sequence similarities | Belongs to the IspH family. |
| Sequence caution | The sequence BAA10159.1 differs from that shown. Reason: Erroneous initiation. |
