ID ISPH_BACC3 Reviewed; 316 AA. AC C1ESI2; DT 28-JUL-2009, integrated into UniProtKB/Swiss-Prot. DT 26-MAY-2009, sequence version 1. DT 28-JUL-2009, entry version 4. DE RecName: Full=4-hydroxy-3-methylbut-2-enyl diphosphate reductase; DE EC=1.17.1.2; GN Name=ispH; OrderedLocusNames=BCA_4399; OS Bacillus cereus (strain 03BB102). OC Bacteria; Firmicutes; Bacillales; Bacillaceae; Bacillus; OC Bacillus cereus group. OX NCBI_TaxID=572264; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RA Dodson R.J., Jackson P., Munk A.C., Brettin T., Bruce D., Detter C., RA Tapia R., Han C., Sutton G., Sims D.; RT "Genome sequence of Bacillus cereus 03BB102."; RL Submitted (FEB-2009) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Converts 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate CC into isopentenyl diphosphate (IPP) and dimethylallyl diphosphate CC (DMAPP) (By similarity). CC -!- CATALYTIC ACTIVITY: Isopentenyl diphosphate + NAD(P)(+) + H(2)O = CC (E)-4-hydroxy-3-methylbut-2-en-1-yl diphosphate + NAD(P)H. CC -!- CATALYTIC ACTIVITY: Dimethylallyl diphosphate + NAD(P)(+) + H(2)O CC = (E)-4-hydroxy-3-methylbut-2-en-1-yl diphosphate + NAD(P)H. CC -!- COFACTOR: Binds 1 3Fe-4S cluster (By similarity). CC -!- PATHWAY: Isoprenoid biosynthesis; dimethylallyl-PP biosynthesis; CC dimethylallyl-PP from 1-hydroxy-2-methyl-2-butenyl 4-diphosphate: CC step 1/1. CC -!- PATHWAY: Isoprenoid biosynthesis; isopentenyl-PP biosynthesis via CC DXP pathway; isopentenyl-PP from 1-deoxy-D-xylulose 5-phosphate: CC step 6/6. CC -!- SIMILARITY: Belongs to the ispH family.
