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

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. (262 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.

uppS
Long (C50) chain Z-isoprenyl diphosphate synthase (Z-decaprenyl diphosphate synthase); Catalyzes the sequential condensation of isopentenyl diphosphate (IPP) in the cis configuration with (2Z,6E)-farnesyl diphosphate (Z-FPP or EZ-FPP) generating the 50 carbon product trans,polycis-decaprenyl diphosphate. When (2E,6E)-farnesyl diphosphate (E-FPP or EE-FPP) is used in vitro, both primary products decaprenyl diphosphate and (2E,6E,10E)-geranylgeranyl diphosphate (EEE-GGPP) are synthesized. M.tuberculosis does not synthesize (2E,6E,10Z)- geranylgeranyl diphosphate (EEZ-GGPP) and heptapreny [...]

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.

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.
