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

folPDihydropteroate synthase; Catalyzes the condensation of para-aminobenzoate (pABA) with 6-hydroxymethyl-7,8-dihydropterin diphosphate (DHPt-PP) to form 7,8- dihydropteroate, the immediate precursor of folate derivatives. (284 aa)    
Predicted Functional Partners:
folK
Similar to M. tuberculosis folK, Rv3607c, probable 2-amino-4-hydroxy-6-hydroxymethyldihydropterine pyrophosphokinase, SW:HPPK_MYCTU (O06276) (188 aa); Fasta score E(): 0, 63.2% identity in 190 aa overlap. Similar to others e.g. to the C-terminal half of Streptococcus pneumoniae sulD, bifunctional folate synthesis protein (includes: dihydroneopterin aldolase and 2-amino-4-hydroxy-6-hydroxymethyldihydropteridine pyrophosphokinase), SW:SULD_STRPN (P22291) (270 aa); Fasta score E(): 1.8e-07, 37.8% identity in 135 aa overlap. Previously sequenced as SW:HPPK_MYCLE (O69528) (191 aa); Fasta sc [...]

folB
Putative dihydroneopterin aldolase; 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.

folC
Highly similar to many folylpolyglutamate synthases (EC 6.3.2.17) including: Lactobacillus casei SW:FOLC_LACCA (P15925) (428 aa); Fasta score E(): 0, 34.1% identity in 437 aa overlap and Mycobacterium tuberculosis RV2447C TR:O53174 (EMBL:AL021246) (487 aa); Fasta score E(): 0, 78.7% identity in 483 aa overlap. Contains Pfam match to entry PF01225 Mur_ligase, Mur ligase family. Contains PS01012 Folylpolyglutamate synthase signature 2.

folE
Similar to M. tuberculosis folE, Rv3609c, GTP cyclohydrolase I, SW:GCH1_MYCTU (O06273) (202 aa); Fasta score E(): 0, 82.0% identity in 205 aa overlap. Similar to many e.g. Bacillus subtilis mtrA, GTP cyclohydrolase I, SW:GCH1_BACSU (P19465) (190 aa); Fasta score E(): 0, 59.5% identity in 190 aa overlap. Previously sequenced as SW:GCH1_MYCLE (O69531) (205 aa); Fasta score E(): 0, 100.0% identity in 205 aa overlap. Contains Pfam match to entry PF01227 GTP_cyclohydroI, GTP cyclohydrolase I. Contains PS00859 GTP cyclohydrolase I signature 1. Contains PS00860 GTP cyclohydrolase I signature 2.

folP2
Dihydropteroate synthase; 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 (By similarity).

ftsH
Putative integral membrane peptidase; 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; In the central section; belongs to the AAA ATPase family.

ML0227
Putative membrane protein; Similar to M. tuberculosis Rv3605c, hypothetical protein, TR:O06277 (EMBL:AL123456) (158 aa); Fasta score E(): 0, 85.4% identity in 158 aa overlap. Previously sequenced as TR:O69527 (EMBL:AL023093) (158 aa); Fasta score E(): 0, 100.0% identity in 158 aa overlap. Contains hydrophobic, possible membrane-spanning regions.

gyrB
Putative DNA gyrase subunit B; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to modulate DNA topology and maintain chromosomes in an underwound state. Negative supercoiling favors strand separation, and DNA replication, transcription, recombination and repair, all of which involve strand separation. Also able to catalyze the interconversion of other topological isomers of dsDNA rings, including catenanes and knotted rings. Type II topoisomerases break and join 2 DNA strands simultaneously in an ATP-dependent manner.
