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

idiIsopentenyl-diphosphate Delta-isomerase; Catalyzes the 1,3-allylic rearrangement of the homoallylic substrate isopentenyl (IPP) to its highly electrophilic allylic isomer, dimethylallyl diphosphate (DMAPP). (203 aa)    
Predicted Functional Partners:
idsA2
Rv2173, (MTV021.06), len: 352 aa. Probable idsA2,geranylgeranyl pyrophosphate synthase, similar to many e.g. Q54193 geranylgeranyl pyrophosphate synthase from Streptomyces griseus (425 aa). Contains PS00723 and PS00444Polyprenyl synthetases signature 1 and 2. FASTA scores: sptr|Q54193|Q54193 geranylgeranyl pyrophosphate synthase (425 aa) opt: 744, E(): 0; 39.2% identity in 352 aa overlap.

idsA1
(2E,6E)-farnesyl diphosphate synthase; Catalyzes the condensation of isopentenyl pyrophosphate (IPP) with geranyl diphosphate (GPP) to yield (2E,6E)-farnesyl diphosphate (E,E-FPP). May be used for squalene and possibly sterol biosynthesis. Belongs to the FPP/GGPP synthase family.
  
 
 0.951
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.
    
 0.945
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.

Rv1086
(2Z,6E)-farnesyl diphosphate synthase; Catalyzes the condensation of only one isopentenyl pyrophosphate (IPP) unit in the cis configuration to E-geranyl diphosphate (E-GPP) generating the 15 carbon product (2Z,6E)-farnesyl diphosphate (Z-FPP or EZ-FPP). Z-FPP is the precursor of decaprenyl diphosphate, which has a central role in the biosynthesis of the mycobacterial cell wall.

phyA
Probable phytoene synthase PhyA; Involved in the biosynthesis of carotenoids. Catalyzes the condensation of two molecules of geranylgeranyl diphosphate (GGPP) to give prephytoene diphosphate (PPPP) and the subsequent rearrangement of the cyclopropylcarbinyl intermediate to yield phytoene (By similarity). Belongs to the phytoene/squalene synthase family.
