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.
