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

ispF2C-methyl-D-erythritol 2,4-cyclodiphosphate synthase; 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). Also converts 4-diphosphocytidyl-2-C-methyl-D- erythritol into 2-C-methyl-D-erythritol 3,4-cyclophosphate and CMP. (159 aa)    
Predicted Functional Partners:
ispE
4-diphosphocytidyl-2-C-methylerythritol kinase; Catalyzes the phosphorylation of the position 2 hydroxy group of 4-diphosphocytidyl-2C-methyl-D-erythritol. Phosphorylates isopentenyl phosphate at low rates. Also acts on isopentenol, and, much less efficiently, dimethylallyl alcohol. Dimethylallyl monophosphate does not serve as a substrate.
 
 
 0.999
ispD
4-diphosphocytidyl-2C-methyl-D-erythritol synthase; Catalyzes the formation of 4-diphosphocytidyl-2-C-methyl-D- erythritol from CTP and 2-C-methyl-D-erythritol 4-phosphate (MEP).
  
 0.999
ispG
1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate synthase; Converts 2C-methyl-D-erythritol 2,4-cyclodiphosphate (ME- 2,4cPP) into 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate, using flavodoxin as the reducing agent; Belongs to the IspG family.
 
 
 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).
 
   
 0.990
ispH
4-hydroxy-3-methylbut-2-enyl diphosphate reductase, 4Fe-4S protein; 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. In vitro, can also hydrate acetylenes to aldehydes and ketones via anti-Markovnikov/Markovnikov addition. Belongs to the IspH family.
 
  
 0.985
dxs
1-deoxyxylulose-5-phosphate synthase, thiamine triphosphate-binding, FAD-requiring; 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).
 
   
 0.984
truD
tRNA(Glu) pseudouridine(13) synthase; Responsible for synthesis of pseudouridine from uracil-13 in transfer RNAs.
 
    0.980
ispA
Geranyltranstransferase; Belongs to the FPP/GGPP synthase family.
  
  
 0.925
idi
Isopentenyl diphosphate isomerase; Catalyzes the 1,3-allylic rearrangement of the homoallylic substrate isopentenyl (IPP) to its highly electrophilic allylic isomer, dimethylallyl diphosphate (DMAPP).
      
 0.921
trmD
tRNA m(1)G37 methyltransferase, SAM-dependent; Specifically methylates guanosine-37 in various tRNAs. Belongs to the RNA methyltransferase TrmD family.
