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

lytB2Probable 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. (335 aa)    
Predicted Functional Partners:
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.

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.

idsB
Rv3383c, (MTV004.41c), len: 350 aa. Possible idsB,polyprenyl transferase (polyprenyl diphosphate synthase), similar to many prenyltransferases involved in lipid biosynthesis e.g. Q9RGW1|GTR geranyl transferase from Streptomyces coelicolor (386 aa), FASTA scores: opt: 908,E(): 3.7e-50, (48.8/% identity in 334 aa overlap); Q9KWG0|GGDPS geranyl geranyl diphosphate synthase from Kitasatospora griseola (Streptomyces griseolosporeus) (348 aa), FASTA scores: opt: 801, E(): 2e-43, (41.5% identity in 347 aa overlap); Q9X7V8|SC6A5.12 putative polyprenyl synthetase from Streptomyces coelicolor (3 [...]

idi
Isopentenyl-diphosphate Delta-isomerase; Catalyzes the 1,3-allylic rearrangement of the homoallylic substrate isopentenyl (IPP) to its highly electrophilic allylic isomer, dimethylallyl diphosphate (DMAPP).
    
 0.945
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.

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.

rpsA
30S ribosomal protein S1 RpsA; Binds mRNA, facilitating recognition of most mRNAs by the 30S ribosomal subunit during translation initiation (By similarity). Probably plays a role in trans-translation; binds tmRNA (the product of the ssrA gene). In trans-translation Ala- aminoacylated transfer-messenger RNA (tmRNA, product of the ssrA gene; the 2 termini fold to resemble tRNA(Ala) while it encodes a short internal open reading frame (the tag peptide)) acts like a tRNA, entering the A-site of the ribosome and displacing the stalled mRNA (which is subsequently degraded). The ribosome the [...]

ispD
4-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.

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.
