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

folBProbable dihydroneopterin aldolase FolB (DHNA); Catalyzes the conversion of 7,8-dihydroneopterin to 6- hydroxymethyl-7,8-dihydropterin, 7,8-dihydromonapterin and 7,8- dihydroxanthopterin, respectively, in equal quantities. After longer incubation times the only product is 6-hydroxymethyl-7,8-dihydropterin. (133 aa)

folK

Probable folK,2-amino-4-hydroxy-6-hydroxymethyldihydropterine pyrophosphokinase, equivalent to O69528|HPPK_MYCLE|folk|ML0226MLCB2548.05c 2-amino-4-hydroxy-6-hydroxymethyldihydropteridine pyrophosphokinase from Mycobacterium leprae (191 aa) FASTA scores: opt: 772, E(): 1.2e-44, (63.15% identity in 190 aa overlap). Also similar to many e.g. P71512|HPPK_METEX|folk|FOLA from Methylobacterium extorquens (158 aa), FASTA scores: opt: 292, E(): 1.4e-12,(36.85% identity in 171 aa overlap); O33726|HPPK_STRPY|folk|SPY1100 from Streptococcus pyogenes (166 aa) [...]

folP1
Dihydropteroate synthase; Catalyzes the condensation of para-aminobenzoate (pABA) with 6-hydroxymethyl-7,8-dihydropterin diphosphate (DHPt-PP) to form 7,8- dihydropteroate (H2Pte), the immediate precursor of folate derivatives.

folE
GTP cyclohydrolase I FolE (GTP-ch-I); Rv3609c, (MTCY07H7B.13), len: 202 aa. Probable folE (alternate gene name: gchA), GTP cyclohydrolase I,equivalent to O69531|GCH1_MYCLE|FOLE|ML0223|MLCB2548.08c GTP cyclohydrolase I from Mycobacterium leprae (205 aa) FASTA scores: opt: 1112, E(): 3.8e-63, (81.95% identity in 205 aa overlap). Also highly similar to many e.g. Q9X8I3|GCH1_STRCO|FOLE|SCE9.10c from Streptomyces coelicolor (201 aa), FASTA scores: opt: 873, E(): 4.2e-48,(67.4% identity in 187 aa overlap); Q9KCC7|MTRA|BH1646 from Bacillus halodurans (188 aa), FASTA scores: opt: 757, E(): 8.1 [...]

folP2
Dihydropteroate synthase 2 FolP2 (DHPS 2) (dihydropteroate pyrophosphorylase 2); Has very low affinity for the DHPS substrate 6-hydroxymethyl- 7,8-dihydropterin-pyrophosphate, but can bind the inhibitor dapsone. Seems to lack dihydropteroate synthase activity, and does probably not function in folate metabolism.

ftsH
Membrane-bound protease FtsH (cell division protein); Acts as a processive, ATP-dependent zinc metallopeptidase for both cytoplasmic and membrane proteins. Plays a role in the quality control of integral membrane proteins.
  
  
 0.963
folC
Probable folylpolyglutamate synthase protein FolC (folylpoly-gamma-glutamate synthetase) (FPGS); Catalyzes the addition of a glutamate residue to dihydropteroate (7,8-dihydropteroate or H2Pte) to form dihydrofolate (7,8-dihydrofolate monoglutamate or H2Pte-Glu). Also catalyzes successive additions of L-glutamate to tetrahydrofolate, leading to folylpolyglutamate derivatives (By similarity).

Rv3605c
Rv3605c, (MTCY07H7B.17), len: 158 aa. Probable conserved secreted or membrane protein, identical to O69527|MLCB2548.04c|ML0227 putative membrane protein from Mycobacterium leprae (158 aa), FASTA scores: opt: 944, E(): 2.6e-56, (85.45% identity in 158 aa overlap).

A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004).

kdtB
Phosphopantetheine adenylyltransferase; Reversibly transfers an adenylyl group from ATP to 4'- phosphopantetheine, yielding dephospho-CoA (dPCoA) and pyrophosphate. Belongs to the bacterial CoaD family.

coaE
Probable dephospho-CoA kinase CoaE (dephosphocoenzyme a kinase); Catalyzes the phosphorylation of the 3'-hydroxyl group of dephosphocoenzyme A to form coenzyme A.
