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:
some 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

pkaPeptidyl-lysine acetyltransferase; Catalyzes the acetyl-CoA-dependent acetylation of lysine residues of a large number of target proteins. Acetylates RNase R in exponential phase cells and RNase II Required for the glucose-dependent acetylation on multiple lysines of alpha, beta and beta' RNAP subunits . Also acetylates acetyl-coenzyme A synthetase (Acs) and the chromosomal replication initiator protein DnaA, and inhibits their activity . Overexpression leads to the acetylation of a large number of additional proteins and inhibits motility (886 aa)    
Predicted Functional Partners:
dhaM
Putative dihydroxyacetone-specific pts enzymes: hpr, ei components; Component of the dihydroxyacetone kinase complex, which is responsible for the phosphoenolpyruvate (PEP)-dependent phosphorylation of dihydroxyacetone. DhaM serves as the phosphoryl donor. Is phosphorylated by phosphoenolpyruvate in an EI- and HPr-dependent reaction, and a phosphorelay system on histidine residues finally leads to phosphoryl transfer to DhaL and dihydroxyacetone

acs
Acetyl-coa synthetase (amp-forming); Catalyzes the conversion of acetate into acetyl-CoA (AcCoA), an essential intermediate at the junction of anabolic and catabolic pathways. Acs undergoes a two-step reaction. In the first half reaction, Acs combines acetate with ATP to form acetyl-adenylate (AcAMP) intermediate. In the second half reaction, it can then transfer the acetyl group from AcAMP to the sulfhydryl group of CoA, forming the product AcCoA
 
  
 0.928
cobB
Deacetylase of acs and chey, chemotaxis regulator; NAD-dependent lysine deacetylase and desuccinylase that specifically removes acetyl and succinyl groups on target proteins. Modulates the activities of several proteins which are inactive in their acylated form. Activates the enzyme acetyl-CoA synthetase by deacetylating 'Lys-609' in the inactive, acetylated form of the enzyme. May also modulate the activity of other propionyl-adenosine monophosphate (AMP)-forming enzymes
   
 
 0.927
pheA
Fused chorismate mutase/prephenate dehydratase; Catalyzes the Claisen rearrangement of chorismate to prephenate and the decarboxylation/dehydration of prephenate to phenylpyruvate
   
 
 0.902
pta
Phosphate acetyltransferase; Involved in acetate metabolism. Catalyzes the reversible interconversion of acetyl-CoA and acetyl phosphate. The direction of the overall reaction changes depending on growth conditions. On minimal medium acetyl-CoA is generated. In rich medium acetyl-CoA is converted to acetate and allowing the cell to dump the excess of acetylation potential in exchange for energy in the form of ATP
  
  
 0.898
yjaB
Gnat-family putative n-acetyltransferase; N-epsilon-lysine acetyltransferase that catalyzes acetylation of a large number of proteins . Binds acetyl-CoA
     
 0.878
yiaC
Putative acyltransferase with acyl-coa n-acyltransferase domain; N-epsilon-lysine acetyltransferase that catalyzes acetylation of a large number of proteins. Overexpression inhibits motility
     
 0.875
ulaR
Deor family transcriptional regulator, ulag and ulaabcdef operon transcriptional repressor; Represses ulaG and the ulaABCDEF operon. Two ulaR binding sites have been identified in each promoter. Full activity requires simultaneous interaction of UlaR with both divergent promoters and seems to be dependent on repressor-mediated DNA loop formation, which is helped by the action of integration host factor
    
   0.869
pfo
Pyruvate-ferredoxin/flavodoxin oxidoreductase; Oxidoreductase required for the transfer of electrons from pyruvate to flavodoxin
