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

yfhMBacterial alpha2-macroglobulin colonization factor ECAM; Protects the bacterial cell from host peptidases. Acts by a 'trapping' mechanism. Cleavage of the bait-region domain by host peptidases leads to a global conformational change, which results in entrapment of the host peptidase and activation of the thioester bond that covalently binds the attacking host peptidase. Trapped peptidases are still active except against very large substrates. May protect the entire periplam, including the lipoproteins anchored to the periplasmic side of the outer membrane, against intruding endopeptidases. (1653 aa)    
Predicted Functional Partners:
pbpC
Penicillin-insensitive murein repair transglycosylase; Cell wall formation. The enzyme has a penicillin-insensitive transglycosylase N-terminal domain (formation of linear glycan strands) and a transpeptidase C-terminal domain which may not be functional.
   
 0.997
nrdR
Nrd regulon repressor; Represses transcription of the class Ib RNR genes nrdHIEF but has much smaller effect on transcription of the class Ia RNR genes nrdAB and class III RNR genes nrdDG. By binding to nrdR boxes in the promoter regions to alter promoter activity, nrdR differentially regulates nrdAB, nrdHIEF and nrdD transcription in aerobic growth.
    
 
 0.778
yfaT
Uncharacterized protein YfaT; Pseudogene, bacterial alpha2-macroglobulin YfaS variant family; putative membrane protein; To P.aeruginosa PA4490 and T.maritima TM0986.
  
  
 0.717
yfaA
DUF2138 family protein, putative host defense protein.
  
  
 0.695
yfaP
DUF2135 family protein, putative host defense protein.
  
  
 0.679
yfaQ
Tandem DUF2300 domain protein, putative host defense protein.
  
  
 0.589
yjiK
SdiA-regulated family putative membrane-anchored protein; putative phytase-like esterase.
  
   
 0.581
creD
Inner membrane protein; Tolerance to colicin E2.
  
     0.546
ulaR
Transcriptional repressor for the L-ascorbate utilization divergent operon; 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.
    
   0.532
sseA
3-mercaptopyruvate sulfurtransferase; Transfers a sulfur ion to cyanide or to other thiol compounds. Also has weak rhodanese activity (130-fold lower). Its participation in detoxification of cyanide may be small. May be involved in the enhancement of serine sensitivity.
