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

plu3971SH3b domain-containing protein; Unnamed protein product; Similar to putative exported protein YgiM of Escherichia coli. (206 aa)    
Predicted Functional Partners:
cca
2',3'-cyclic phosphodiesterase; Catalyzes the addition and repair of the essential 3'- terminal CCA sequence in tRNAs without using a nucleic acid template. Adds these three nucleotides in the order of C, C, and A to the tRNA nucleotide-73, using CTP and ATP as substrates and producing inorganic pyrophosphate. Also shows phosphatase, 2'-nucleotidase and 2',3'-cyclic phosphodiesterase activities. These phosphohydrolase activities are probably involved in the repair of the tRNA 3'-CCA terminus degraded by intracellular RNases.

plu0491
Unnamed protein product; Highly similar to unknown protein YjaG of Escherichia coli.
  
     0.686
plu3995
Unnamed protein product; Similar to unknown protein YqjE of Escherichia coli.
  
     0.660
cysZ
Sulfate transport protein CysZ; High affinity, high specificity proton-dependent sulfate transporter, which mediates sulfate uptake. Provides the sulfur source for the cysteine synthesis pathway; Belongs to the CysZ family.
 
     0.630
rseA
Sigma-E factor negative regulatory protein; An anti-sigma factor for extracytoplasmic function (ECF) sigma factor sigma-E (RpoE). ECF sigma factors are held in an inactive form by an anti-sigma factor until released by regulated intramembrane proteolysis (RIP). RIP occurs when an extracytoplasmic signal triggers a concerted proteolytic cascade to transmit information and elicit cellular responses. The membrane-spanning regulatory substrate protein is first cut periplasmically (site-1 protease, S1P, DegS), then within the membrane itself (site-2 protease, S2P, RseP), while cytoplasmic p [...]

hemY
HemY protein; Involved in a late step of protoheme IX synthesis.
  
     0.597
hemX
uroporphyrin-III C-methyltransferase (urogen III methylase).
  
     0.572
plu4553
Unnamed protein product; Similar to unknown protein YtfN of Escherichia coli.
 
     0.529
rseB
Sigma-E factor regulatory protein RseB precursor.
 
    0.524
ftsL
Cell division protein; Essential cell division protein. May link together the upstream cell division proteins, which are predominantly cytoplasmic, with the downstream cell division proteins, which are predominantly periplasmic.
