ID ISPF_ECOSE Reviewed; 159 AA. AC B6I6D6; DT 24-MAR-2009, integrated into UniProtKB/Swiss-Prot. DT 16-DEC-2008, sequence version 1. DT 31-MAY-2011, entry version 24. DE RecName: Full=2-C-methyl-D-erythritol 2,4-cyclodiphosphate synthase; DE Short=MECDP-synthase; DE Short=MECPS; DE EC=4.6.1.12; GN Name=ispF; OrderedLocusNames=ECSE_2998; OS Escherichia coli (strain SE11). OC Bacteria; Proteobacteria; Gammaproteobacteria; Enterobacteriales; OC Enterobacteriaceae; Escherichia. OX NCBI_TaxID=409438; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=SE11; RX PubMed=18931093; DOI=10.1093/dnares/dsn026; RA Oshima K., Toh H., Ogura Y., Sasamoto H., Morita H., Park S.-H., RA Ooka T., Iyoda S., Taylor T.D., Hayashi T., Itoh K., Hattori M.; RT "Complete genome sequence and comparative analysis of the wild-type RT commensal Escherichia coli strain SE11 isolated from a healthy RT adult."; RL DNA Res. 15:375-386(2008). CC -!- FUNCTION: Converts 4-diphosphocytidyl-2-C-methyl-D-erythritol 2- CC phosphate into 2-C-methyl-D-erythritol 2,4-cyclodiphosphate CC (MECDP) and CMP (By similarity). CC -!- CATALYTIC ACTIVITY: 2-phospho-4-(cytidine 5'-diphospho)-2-C- CC methyl-D-erythritol = 2-C-methyl-D-erythritol 2,4-cyclodiphosphate CC + CMP. CC -!- COFACTOR: Binds 1 divalent metal cation per subunit (By CC similarity). CC -!- PATHWAY: Isoprenoid biosynthesis; isopentenyl diphosphate CC biosynthesis via DXP pathway; isopentenyl diphosphate from 1- CC deoxy-D-xylulose 5-phosphate: step 4/6. CC -!- SUBUNIT: Homotrimer (By similarity). CC -!- SIMILARITY: Belongs to the IspF family.
