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

Score
ydiUSerine/tyrosine/threonine adenylyltransferase; Catalyzes the transfer of adenosine 5'-monophosphate (AMP) to Ser, Thr and Tyr residues of target proteins (AMPylation). Cannot use GTP, CTP or UTP as cosubstrate. AMPylates SucA at 'Thr-405' and GrxA on 'Tyr-13'. Regulates protein S-glutathionylation levels probably by AMPylation of deglutathionylation enzymes such as GrxA. Probably involved in redox homeostasis (478 aa)    
Predicted Functional Partners:
btuC
Vitamin b12 transport system permease protein; Part of the ABC transporter complex BtuCDF involved in vitamin B12 import. Involved in the translocation of the substrate across the membrane
    
 0.780
btuD
Vitamin b12 transport system atp-binding protein; Part of the ABC transporter complex BtuCDF involved in vitamin B12 import. Responsible for energy coupling to the transport system
     
 0.731
araJ
Mfs transporter, dha1 family, arabinose polymer utilization protein; May be involved in either the transport or processing of arabinose polymers
   
  
 0.687
ydiV
anti-FlhD4C2 factor, inactive EAL family phosphodiesterase; Upon overexpression acts as a novel anti-FlhC(2)FlhD(4) factor, decreasing its DNA-binding activity, able to negatively regulate expression of flagellar class II operons including FliC
       0.651
cfa
Cyclopropane fatty acyl phospholipid synthase, sam-dependent; Transfers a methylene group from S-adenosyl-L-methionine to the cis double bond of an unsaturated fatty acid chain resulting in the replacement of the double bond with a methylene bridge
      
 0.609
ppsR
[pyruvate, water dikinase]-phosphate phosphotransferase / [pyruvate, water dikinase] kinase; Bifunctional serine/threonine kinase and phosphorylase involved in the regulation of the phosphoenolpyruvate synthase (PEPS) by catalyzing its phosphorylation/dephosphorylation
      
 0.603
uup
Probably plays a role in ribosome assembly or function; overexpression suppresses cold-sensitive growth of a bipA deletion (Probable). May be involved in resolution of branched DNA intermediates that result from template switching in postreplication gaps. Binds DNA at Holliday junctions. May be involved in the correct segregation of nucleoids . Has ATPase activity, binds DNA non-sequence specifically; the presence of DNA does not change the ATPase activity . Mutations in this gene cause an increase in RecA-independent precise excision of transposons and insertion elements, and also red [...]

hybO
Hydrogenase 2, small subunit; This is one of three E.coli hydrogenases synthesized in response to different physiological conditions. HYD2 is involved in hydrogen uptake
      
 0.503
sdaB
L-serine dehydratase 2; Deaminates also threonine, particularly when it is present in high concentration
      
 0.478
iscR
Rrf2 family transcriptional regulator, iron-sulfur cluster assembly transcription factor; Regulates the transcription of several operons and genes involved in the biogenesis of Fe-S clusters and Fe-S-containing proteins. Transcriptional repressor of the iscRSUA operon, which is involved in the assembly of Fe-S clusters into Fe-S proteins. In its apoform, under conditions of oxidative stress or iron deprivation, it activates the suf operon, which is a second operon involved in the assembly of Fe-S clusters. Represses its own transcription as well as that of toxin rnlA
