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

abgTP-aminobenzoyl-glutamate transporter; Essential for aminobenzoyl-glutamate utilization. It catalyzes the concentration-dependent uptake of p-aminobenzoyl- glutamate (PABA-GLU) into the cell and allows accumulation of PABA-GLU to a concentration enabling AbgAB to catalyze cleavage into p- aminobenzoate and glutamate. It seems also to increase the sensitivity to low levels of aminobenzoyl-glutamate. May actually serve physiologically as a transporter for some other molecule, perhaps a dipeptide, and that it transports p-aminobenzoyl-glutamate as a secondary activity. The physiological ro [...] (508 aa)    
Predicted Functional Partners:
abgA
P-aminobenzoyl-glutamate hydrolase, A subunit; Component of the p-aminobenzoyl-glutamate hydrolase multicomponent enzyme system which catalyzes the cleavage of p- aminobenzoyl-glutamate (PABA-GLU) to form p-aminobenzoate (PABA) and glutamate. AbgAB does not degrade dipeptides and the physiological role of abgABT should be clarified; Belongs to the peptidase M20 family.
 
  
 0.996
abgB
P-aminobenzoyl-glutamate hydrolase, B subunit; Component of the p-aminobenzoyl-glutamate hydrolase multicomponent enzyme system which catalyzes the cleavage of p- aminobenzoyl-glutamate (PABA-GLU) to form p-aminobenzoate (PABA) and glutamate. AbgAB does not degrade dipeptides and the physiological role of abgABT should be clarified.
  
 0.989
abgR
Putative DNA-binding transcriptional regulator of abgABT operon; Could be the regulator of the abg operon; Belongs to the LysR transcriptional regulatory family.
 
  
 0.907
ogt
O-6-alkylguanine-DNA:cysteine-protein methyltransferase; Involved in the cellular defense against the biological effects of O6-methylguanine (O6-MeG) and O4-methylthymine (O4-MeT) in DNA. Repairs the methylated nucleobase in DNA by stoichiometrically transferring the methyl group to a cysteine residue in the enzyme. This is a suicide reaction: the enzyme is irreversibly inactivated.
  
  
 0.871
pabA
Aminodeoxychorismate synthase, subunit II; Part of a heterodimeric complex that catalyzes the two-step biosynthesis of 4-amino-4-deoxychorismate (ADC), a precursor of p- aminobenzoate (PABA) and tetrahydrofolate. In the first step, a glutamine amidotransferase (PabA) generates ammonia as a substrate that, along with chorismate, is used in the second step, catalyzed by aminodeoxychorismate synthase (PabB) to produce ADC. PabA converts glutamine into glutamate only in the presence of stoichiometric amounts of PabB.
      
 0.809
yfcC
Putative inner membrane transporter; Metabolomic profiling of different yfcC over-expression and deletion strains suggests that it may affect the glyoxylate shunt. To H.influenzae HI_0594.
  
     0.550
fnr
Oxygen-sensing anaerobic growth regulon transcriptional regulator FNR; Global transcription factor that controls the expression of over 100 target genes in response to anoxia. It facilitates the adaptation to anaerobic growth conditions by regulating the expression of gene products that are involved in anaerobic energy metabolism. When the terminal electron acceptor, O(2), is no longer available, it represses the synthesis of enzymes involved in aerobic respiration and increases the synthesis of enzymes required for anaerobic respiration.

yahN
Amino acid exporter for proline, lysine, glutamate, homoserine; Putative cytochrome subunit of dehydrogenase.
      
 0.451
kdgT
2-keto-3-deoxy-D-gluconate transporter; The 2-keto-3-deoxygluconate permease transports the degraded pectin products into the bacterial cell, where they serve as carbon and energy sources. This is a hydrogen coupled transport system; Belongs to the KdgT transporter family.

ykgO
RpmJ-like protein.
