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

kdpBPotassium-transporting ATPase ATP-binding subunit; Part of the high-affinity ATP-driven potassium transport (or Kdp) system, which catalyzes the hydrolysis of ATP coupled with the electrogenic transport of potassium into the cytoplasm. This subunit is responsible for energy coupling to the transport system. Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IA subfamily. (709 aa)    
Predicted Functional Partners:
kdpA
Potassium-transporting ATPase potassium-binding subunit; Part of the high-affinity ATP-driven potassium transport (or Kdp) system, which catalyzes the hydrolysis of ATP coupled with the electrogenic transport of potassium into the cytoplasm. This subunit binds and transports the potassium across the cytoplasmic membrane.

kdpC
Potassium-transporting ATPase KdpC subunit; Part of the high-affinity ATP-driven potassium transport (or Kdp) system, which catalyzes the hydrolysis of ATP coupled with the electrogenic transport of potassium into the cytoplasm. This subunit acts as a catalytic chaperone that increases the ATP-binding affinity of the ATP-hydrolyzing subunit KdpB by the formation of a transient KdpB/KdpC/ATP ternary complex.
 
 0.999
kdpD
Probable sensor protein KdpD; Member of the two-component regulatory system KdpD/KdpE involved in the regulation of the kdp operon. Functions as a sensor protein kinase which is autophosphorylated at a histidine residue and transfers its phosphate group to the conserved aspartic acid residue in the regulatory domain of KdpE in response to environmental signals such as low levels of potassium ion, osmotic imbalance, acid and nutrient stresses. In turn, KdpE binds to the upstream promoter regions of target genes to positively regulate their expression.
 
  
 0.992
kdpF
Rv1028A, len: 30 aa. Probable kdpF, membrane protein, showing similarity with P36937|KDPF_ECOLI|B0698.1 protein KDPF from Escherichia coli strain K12 (see citation below) (27% identity); and KdpF protein from Streptomyces coelicolor (51% identity).
  
  
 0.962
kdpE
Probable transcriptional regulatory protein KdpE; Member of the two-component regulatory system KdpD/KdpE involved in the regulation of the kdp operon. Upon phosphorylation by KdpD, functions as a transcription regulator by direct binding to promoter regions of target genes to positively regulate their expression.

Rv0584
Rv0584, (MTV039.22), len: 877 aa. Possible conserved exported protein, similar to other hypothetical proteins which are not necessarily secreted e.g. CAB61925.1|AL133278 putative secreted protein from Streptomyces coelicolor (772 aa); AAD51075.1|AF175722_1|AF175722 immunoreactive 89kD antigen PG87 from Porphyromonas gingivalis (781 aa), FASTA scores: opt: 637, E(): 2.1e-30, (29.1% identity in 794 aa overlap); etc. Contains PS00699 Nitrogenases component 1 alpha and beta subunits signature 1. Has potential N-terminal signal peptide. Predicted to be an outer membrane protein (See Song et [...]

Rv2181
Alpha(1->2)mannosyltransferase; Responsible for the addition of alpha-(1-2) mannose branches to the linear mannan core on the biosynthetic pathway to mature lipoarabinomannan (LAM).
   
    0.416
trcR
Rv1033c, (MTCY10G2.16), len: 257 aa. TrcR,two-component regulatory protein (see citations below),similar to Q50825 two component response regulator from Mycobacterium tuberculosis (234 aa), FASTA scores: opt: 628, E(): 0, (46.0% identity in 226 aa overlap). Note that in vitro autophosphorylation of TrcS requires the presence of Mn2+or Ca2+as a divalent cation cofactor and subsequent transphosphorylation of TrcR is evident in the presence of TrcS-phosphate and Ca2+.

nadB
Probable L-aspartate oxidase NadB; Catalyzes the oxidation of L-aspartate to iminoaspartate.
