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 03-SEP-2014, entry version 41. 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; Bacilli; Bacillales; Bacillaceae; Bacillus; OC Bacillus cereus group. OX NCBI_TaxID=572264; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=03BB102; 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 per subunit (By similarity). CC -!- PATHWAY: Isoprenoid biosynthesis; dimethylallyl diphosphate CC biosynthesis; dimethylallyl diphosphate from (2E)-4-hydroxy-3- CC methylbutenyl diphosphate: step 1/1. CC -!- PATHWAY: Isoprenoid biosynthesis; isopentenyl diphosphate CC biosynthesis via DXP pathway; isopentenyl diphosphate from 1- CC deoxy-D-xylulose 5-phosphate: step 6/6. CC -!- SIMILARITY: Belongs to the IspH family.
