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

tatBTatABCE protein translocation system subunit; Part of the twin-arginine translocation (Tat) system that transports large folded proteins containing a characteristic twin- arginine motif in their signal peptide across membranes. Together with TatC, TatB is part of a receptor directly interacting with Tat signal peptides. TatB may form an oligomeric binding site that transiently accommodates folded Tat precursor proteins before their translocation. (171 aa)    
Predicted Functional Partners:
tatE
Sec-independent protein translocase protein TatE; Part of the twin-arginine translocation (Tat) system that transports large folded proteins containing a characteristic twin- arginine motif in their signal peptide across membranes. TatE shares overlapping functions with TatA; Belongs to the TatA/E family. TatE subfamily.
 
 0.999
tatA
TatABCE protein translocation system subunit; Part of the twin-arginine translocation (Tat) system that transports large folded proteins containing a characteristic twin- arginine motif in their signal peptide across membranes. TatA could form the protein-conducting channel of the Tat system. Belongs to the TatA/E family.
 
 0.999
tatC
TatABCE protein translocation system subunit; Part of the twin-arginine translocation (Tat) system that transports large folded proteins containing a characteristic twin- arginine motif in their signal peptide across membranes. Together with TatB, TatC is part of a receptor directly interacting with Tat signal peptides.

ftsP
Septal ring component that protects the divisome from stress; Cell division protein that is required for growth during stress conditions. May be involved in protecting or stabilizing the divisomal assembly under conditions of stress.
   
 
 0.984
tatD
Quality control of Tat-exported FeS proteins; 3'-5' exonuclease that prefers single-stranded DNA and RNA. May play a role in the H(2)O(2)-induced DNA damage repair. Belongs to the metallo-dependent hydrolases superfamily. TatD-type hydrolase family. TatD subfamily.

guaA
GMP synthetase (glutamine aminotransferase); Catalyzes the synthesis of GMP from XMP.
  
  
 0.900
torA
Trimethylamine N-oxide (TMAO) reductase I, catalytic subunit; Reduces trimethylamine-N-oxide (TMAO) into trimethylamine; an anaerobic reaction coupled to energy-yielding reactions.
     
 0.881
ubiE
Ubiquinone/menaquinone biosynthesis C-methyltransferase UbiE; Methyltransferase required for the conversion of demethylmenaquinol (DMKH2) to menaquinol (MKH2) and the conversion of 2-polyprenyl-6-methoxy-1,4-benzoquinol (DDMQH2) to 2-polyprenyl-3- methyl-6-methoxy-1,4-benzoquinol (DMQH2).
  
  
 0.837
flk
Putative flagella assembly protein; Acts as a regulator of flagellar gene expression by modulating the protein level of the anti sigma factor FlgM upon sensing ring completion or hook elongation. Flk could inhibit FlgM secretion by acting as a braking system for the flagellar-associated type III secretion (T3S) system. Plays a role in hindering to flip the flagellar T3S specificity switch from the rod and hook-type substrates to filament-type substrates prior to hook-basal body (HBB) completion possibly by preventing interaction of FliK with FlhB (By similarity).
   
  
 0.816
secB
Protein export chaperone; One of the proteins required for the normal export of some preproteins out of the cell cytoplasm. It is a molecular chaperone that binds to a subset of precursor proteins, maintaining them in a translocation-competent state. For 2 proteins (MBP, MalE and PhoA) the substrate is wrapped around the homotetramer, which prevents it from folding. It also specifically binds to its receptor SecA. Its substrates include DegP, FhuA, FkpA, GBP, LamB, MalE (MBP), OmpA, OmpF, OmpT, OmpX, OppA, PhoE, TolB, TolC, YbgF, YcgK, YgiW and YncE.
