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

malTMal 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. (901 aa)    
Predicted Functional Partners:
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, [...]

ibpB
Heat shock chaperone; Associates with aggregated proteins, together with IbpA, to stabilize and protect them from irreversible denaturation and extensive proteolysis during heat shock and oxidative stress. Aggregated proteins bound to the IbpAB complex are more efficiently refolded and reactivated by the ATP-dependent chaperone systems ClpB and DnaK/DnaJ/GrpE. Its activity is ATP-independent.
    
 
 0.849
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.
      
 0.813
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 [...]
      
 0.811
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.
      
 0.804
lamB
Maltose outer membrane porin (maltoporin); Involved in the transport of maltose and maltodextrins, indispensable for translocation of dextrins containing more than three glucosyl moieties. A hydrophobic path ('greasy slide') of aromatic residues serves to guide and select the sugars for transport through the channel. Also acts as a receptor for several bacteriophages including lambda.
 
  
 0.777
malE
Maltose transporter subunit; Part of the ABC transporter complex MalEFGK involved in maltose/maltodextrin import. Binds maltose and higher maltodextrins such as maltotriose. Belongs to the bacterial solute-binding protein 1 family.
 
    0.752
feoC
Putative DNA-binding transcriptional regulator; May function as a transcriptional regulator that controls feoABC expression; Belongs to the FeoC family.
      
 0.739
malF
Maltose transporter subunit; Part of the ABC transporter complex MalEFGK involved in maltose/maltodextrin import. Probably responsible for the translocation of the substrate across the membrane.
  
    0.732
gatY
D-tagatose 1,6-bisphosphate aldolase 2, catalytic subunit; Catalytic subunit of the tagatose-1,6-bisphosphate aldolase GatYZ, which catalyzes the reversible aldol condensation of dihydroxyacetone phosphate (DHAP or glycerone-phosphate) with glyceraldehyde 3-phosphate (G3P) to produce tagatose 1,6-bisphosphate (TBP). Requires GatZ subunit for full activity and stability. Is involved in the catabolism of galactitol.
