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

ogtO-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. (171 aa)    
Predicted Functional Partners:
alkA
3-methyl-adenine DNA glycosylase II; Hydrolysis of the deoxyribose N-glycosidic bond to excise 3- methyladenine, 3-methylguanine, 7-methylguanine, O2-methylthymine, and O2-methylcytosine from the damaged DNA polymer formed by alkylation lesions.

abgT
P-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 [...]

uspE
Stress-induced protein; Required for resistance to DNA-damaging agents.
 
  
 0.846
alkB
Oxidative demethylase of N1-methyladenine or N3-methylcytosine DNA lesions; Dioxygenase that repairs alkylated DNA and RNA containing 3- methylcytosine or 1-methyladenine by oxidative demethylation. Has highest activity towards 3-methylcytosine. Has lower activity towards alkylated DNA containing ethenoadenine, and no detectable activity towards 1-methylguanine or 3-methylthymine. Accepts double-stranded and single-stranded substrates. Requires molecular oxygen, alpha- ketoglutarate and iron. Provides extensive resistance to alkylating agents such as MMS and DMS (SN2 agents), but not t [...]

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.
  
  
 0.832
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.

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.

lpxB
tetraacyldisaccharide-1-P synthase; Condensation of UDP-2,3-diacylglucosamine and 2,3- diacylglucosamine-1-phosphate to form lipid A disaccharide, a precursor of lipid A, a phosphorylated glycolipid that anchors the lipopolysaccharide to the outer membrane of the cell; Belongs to the LpxB family.
      0.753
aidB
DNA alkylation damage repair protein; Part of the adaptive DNA-repair response to alkylating agents. Could prevent alkylation damage by protecting DNA and destroying alkylating agents that have yet to reach their DNA target. Binds to double-stranded DNA with a preference for a DNA region that includes its own promoter. Shows weak isovaleryl-CoA dehydrogenase activity in vitro.
      
 0.733
abgR
Putative DNA-binding transcriptional regulator of abgABT operon; Could be the regulator of the abg operon; Belongs to the LysR transcriptional regulatory family.
