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

feoCPutative DNA-binding transcriptional regulator; May function as a transcriptional regulator that controls feoABC expression; Belongs to the FeoC family. (78 aa)    
Predicted Functional Partners:
feoB
Ferrous iron transporter protein B and GTP-binding protein; Transporter of a GTP-driven Fe(2+) uptake system, probably couples GTP-binding to channel opening and Fe(2+) uptake. A guanine nucleotide-binding protein (G proteins) in which the guanine nucleotide binding site alternates between an active, GTP-bound state and an inactive, GDP- bound state. This protein has fast intrinsic GDP release, mediated by the G5 loop (about residues 149-158). Presumably GTP hydrolysis leads to conformational changes and channel closing. A GDP release mechanism involving a conformational change of the [...]

feoA
Ferrous iron transporter, protein A; Involved in Fe(2+) ion uptake. Does not stimulate the GTPase activity of the N-terminus of FeoB (residues 1- 276).
  
  
 0.988
malT
Mal regulon transcriptional activator; Positively regulates the transcription of the maltose regulon whose gene products are responsible for uptake and catabolism of malto- oligosaccharides. Specifically binds to the promoter region of its target genes, recognizing a short DNA motif called the MalT box (5'- GGA[TG]GA-3'). Displays weak ATPase activity, but this activity is not required for promoter binding.

yhgA
Transposase_31 family protein; A low activity DNA endonuclease yielding 3'-hydroxyl ends, equally active on ss or dsDNA, not active on dsRNA. Shows no sequence specificity. Upon expression enhances RecA-independent DNA recombination 49-fold, concomitantly reducing viability by 88% and probably inducing DNA damage as measured by induction of the SOS repair response in RecA cells. RecA-independent DNA recombination leads to replacement of recipient genes with large segments of donor DNA rather than DNA addition to the donor strain; increased expression of RpnA leads to smaller replacemen [...]

ygeX
2,3-diaminopropionate ammonia lyase, PLP-dependent; Catalyzes the alpha,beta-elimination reaction of both L- and D-alpha,beta-diaminopropionate (DAP) to form pyruvate and ammonia. In vitro the D-isomer of serine is degraded to pyruvate, though very poorly; other amino acids (L-serine, D- and L-threonine, D- and L-beta- Cl-alanine) are not substrates. In vivo allows poor growth on L-DAP or a DL-DAP mixture but not on D-DAP alone, this may be due to a poor promoter. DL-DAP is toxic in the absence of this enzyme, it may inhibit enzymes involved in the synthesis of pyruvate and aspartate, [...]

exbD
Membrane spanning protein in TonB-ExbB-ExbD complex; Involved in the TonB-dependent energy-dependent transport of various receptor-bound substrates.
   
  
 0.594
exbB
Membrane spanning protein in TonB-ExbB-ExbD complex; Involved in the TonB-dependent energy-dependent transport of various receptor-bound substrates. Protects ExbD from proteolytic degradation and functionally stabilizes TonB.
   
  
 0.565
hcaB
2,3-dihydroxy-2,3-dihydrophenylpropionate dehydrogenase; Converts 3-phenylpropionate-dihydrodiol (PP-dihydrodiol) and cinnamic acid-dihydrodiol (CI-dihydrodiol) into 3-(2,3- dihydroxylphenyl)propanoic acid (DHPP) and 2,3-dihydroxicinnamic acid (DHCI), respectively; Belongs to the short-chain dehydrogenases/reductases (SDR) family.
      
 0.543
mntH
Manganese/divalent cation transporter; H(+)-stimulated, divalent metal cation uptake system. Involved in manganese and iron uptake. Can also transport cadmium, cobalt, zinc and to a lesser extent nickel and copper. Involved in response to reactive oxygen.
   
  
 0.531
fucI
L-fucose isomerase; Converts the aldose L-fucose into the corresponding ketose L- fuculose. Is also able to convert D-arabinose into D-ribulose, but this isomerase has a higher affinity for fucose and fuculose than for arabinose and ribulose, respectively.
