DE RecName: Full=4-hydroxy-3-methylbut-2-enyl diphosphate reductase; DE EC=1.17.1.2; GN Name=ispH; OrderedLocusNames=Mpe_A2693; OS Methylibium petroleiphilum (strain PM1). OC Bacteria; Proteobacteria; Betaproteobacteria; Burkholderiales; OC Methylibium. OX NCBI_TaxID=420662; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=PM1; RX PubMed=17158667; DOI=10.1128/JB.01259-06; RA Kane S.R., Chakicherla A.Y., Chain P.S.G., Schmidt R., Shin M.W., RA Legler T.C., Scow K.M., Larimer F.W., Lucas S.M., Richardson P.M., RA Hristova K.R.; RT "Whole-genome analysis of the methyl tert-butyl ether-degrading beta- RT proteobacterium Methylibium petroleiphilum PM1."; RL J. Bacteriol. 189:1931-1945(2007). 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 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.
