STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

ispD4-diphosphocytidyl-2C-methyl-D-erythritol synthase IspD (MEP cytidylyltransferase) (MCT); Catalyzes the formation of 4-diphosphocytidyl-2-C-methyl-D- erythritol from CTP and 2-C-methyl-D-erythritol 4-phosphate (MEP). Belongs to the IspD/TarI cytidylyltransferase family. IspD subfamily. (231 aa)    
Predicted Functional Partners:
ispF
Probable 2C-methyl-D-erythritol 2,4-cyclodiphosphate synthase IspF (MECPS); Involved in the biosynthesis of isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP), two major building blocks of isoprenoid compounds. Catalyzes the conversion of 4-diphosphocytidyl-2- C-methyl-D-erythritol 2-phosphate (CDP-ME2P) to 2-C-methyl-D-erythritol 2,4-cyclodiphosphate (ME-CPP) with a corresponding release of cytidine 5-monophosphate (CMP).

ispE
4-diphosphocytidyl-2-C-methyl-D-erythritol kinase; Catalyzes the phosphorylation of the position 2 hydroxy group of 4-diphosphocytidyl-2C-methyl-D-erythritol; Belongs to the GHMP kinase family. IspE subfamily.
 
 
 0.998
dxr
1-deoxy-D-xylulose 5-phosphate reductoisomerase; Catalyzes the NADP-dependent rearrangement and reduction of 1-deoxy-D-xylulose-5-phosphate (DXP) to 2-C-methyl-D-erythritol 4- phosphate (MEP); Belongs to the DXR family.
 
 
 0.998
gcpE
Probable GcpE protein; Converts 2C-methyl-D-erythritol 2,4-cyclodiphosphate (ME- 2,4cPP) into 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate. Belongs to the IspG family.
 
  
 0.986
dxs1
1-deoxy-D-xylulose-5-phosphate synthase; Catalyzes the acyloin condensation reaction between C atoms 2 and 3 of pyruvate and glyceraldehyde 3-phosphate to yield 1-deoxy-D- xylulose-5-phosphate (DXP); Belongs to the transketolase family. DXPS subfamily.
 
  
 0.969
carD
Possible transcription factor; Controls rRNA transcription by binding to the RNA polymerase (RNAP). Required for replication and persistence during infection of mice; Belongs to the CarD family.
  
  
 0.955
lytB1
Probable LYTB-related protein LytB1; Catalyzes the conversion of 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate (HMBPP) into a mixture of isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP). Acts in the terminal step of the DOXP/MEP pathway for isoprenoid precursor biosynthesis. Has a reduced activity compared with LytB2. Is unable to functionally complement the loss of lytB2 in M.tuberculosis. Belongs to the IspH family.
 
  
 0.945
lytB2
Probable LYTB-related protein LytB2; Catalyzes the conversion of 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate (HMBPP) into a mixture of isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP). Acts in the terminal step of the DOXP/MEP pathway for isoprenoid precursor biosynthesis. Has a higher activity compared with LytB2. Is essential for M.tuberculosis growth in vitro.
