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

kgdMultifunctional alpha-ketoglutarate metabolic enzyme; Shows three enzymatic activities that share a first common step, the attack of thiamine-PP on 2-oxoglutarate (alpha-ketoglutarate, KG), leading to the formation of an enamine-thiamine-PP intermediate upon decarboxylation. Thus, displays KGD activity, catalyzing the decarboxylation from five-carbon 2-oxoglutarate to four-carbon succinate semialdehyde (SSA). Also catalyzes C-C bond formation between the activated aldehyde formed after decarboxylation of alpha- ketoglutarate and the carbonyl of glyoxylate (GLX), to yield 2-hydroxy- 3-o [...] (1231 aa)    
Predicted Functional Partners:
lpdC
Dihydrolipoyl dehydrogenase; Lipoamide dehydrogenase is an essential component of the alpha-ketoacid dehydrogenase complexes, namely the pyruvate dehydrogenase (PDH) complex, the branched-chain alpha-ketoacid dehydrogenase (BCKADH) complex, and likely also the 2-oxoglutarate dehydrogenase (ODH) complex. Catalyzes the reoxidation of dihydrolipoyl groups which are covalently attached to the lipoate acyltransferase components (E2) of the complexes. Is also able to catalyze the transhydrogenation of NADH and thio-NAD(+) in the absence of D,L- lipoamide, and the NADH-dependent reduction of [...]

Rv0794c
Rv0794c, (MTV042.04c), len: 499 aa. Probable oxidoreductase, possibly dihydrolipoamide dehydrogenase or mercuric reductase. Highly similar to CAB62675.1|AL133422 probable oxidoreductase from Streptomyces coelicolor (477 aa); and similar to various oxidoreductases e.g. P08663|MERA_STAAU mercuric reductase (HG(II) reductase) from Staphylococcus aureus (547 aa); AAK70920.1|AC087551_19|AC087551 putative lipoamide dehydrogenase from Oryza sativa (563 aa); NP_437349.1|NC_003078 putative FAD-dependent pyridine nucleotide-disulphide oxidoreductase, similar to mercuric reductases protein from S [...]

garA
Conserved protein with FHA domain, GarA; Involved in regulation of glutamate metabolism. Acts as a phosphorylation-dependent molecular switch that modulates the activities of Kgd, Gdh and GltB.
  
 
 0.999
bkdB
Probable branched-chain keto acid dehydrogenase E1 component, beta subunit BkdB; Component of the branched-chain alpha-ketoacid dehydrogenase (BCKADH) complex, that catalyzes the overall conversion of branched- chain alpha-ketoacids to acyl-CoA and CO(2).
 
 0.999
sthA
Probable soluble pyridine nucleotide transhydrogenase; Conversion of NADPH, generated by peripheral catabolic pathways, to NADH, which can enter the respiratory chain for energy generation; Belongs to the class-I pyridine nucleotide-disulfide oxidoreductase family.
 
 0.999
mtr
NADPH-dependent mycothiol reductase Mtr; Catalyzes the NAD(P)H-dependent reduction of mycothione (the oxidized disulfide form of mycothiol) to mycothiol. Belongs to the class-I pyridine nucleotide-disulfide oxidoreductase family.
  
 0.999
lpdA
NAD(P)H quinone reductase LpdA; May contribute to virulence by increasing resistance to reactive oxygen intermediates. It can reduce 2,6-dimethyl-1,4- benzoquinone (DMBQ), 5-hydroxy-1,4-naphthaquinone (5-HNQ) and menadione. NADPH is the physiological reductant rather than NADH.

sucC
Probable succinyl-CoA synthetase (beta chain) SucC (SCS-beta); Succinyl-CoA synthetase functions in the citric acid cycle (TCA), coupling the hydrolysis of succinyl-CoA to the synthesis of either ATP or GTP and thus represents the only step of substrate-level phosphorylation in the TCA. The beta subunit provides nucleotide specificity of the enzyme and binds the substrate succinate, while the binding sites for coenzyme A and phosphate are found in the alpha subunit.
 
 0.998
sucD
Probable succinyl-CoA synthetase (alpha chain) SucD (SCS-alpha); Succinyl-CoA synthetase functions in the citric acid cycle (TCA), coupling the hydrolysis of succinyl-CoA to the synthesis of either ATP or GTP and thus represents the only step of substrate-level phosphorylation in the TCA. The alpha subunit of the enzyme binds the substrates coenzyme A and phosphate, while succinate binding and nucleotide specificity is provided by the beta subunit.

dlaT
DlaT, dihydrolipoamide acyltransferase, E2 component of pyruvate dehydrogenase; Component of the pyruvate dehydrogenase (PDH) complex, that catalyzes the overall conversion of pyruvate to acetyl-CoA and CO(2). Appears to be essential for Mtb pathogenesis.
