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

Score
ygfASimilar to E. coli putative ligase (AAC75949.1); Blastp hit to AAC75949.1 (182 aa), 86% identity in aa 1 - 182; Belongs to the 5-formyltetrahydrofolate cyclo-ligase family. (182 aa)    
Predicted Functional Partners:
folD
5,10-methylene-tetrahydrofolate dehydrogenase; Catalyzes the oxidation of 5,10-methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10- methenyltetrahydrofolate to 10-formyltetrahydrofolate.
 
  
 0.952
purN
Polyphosphate kinase; Catalyzes the transfer of a formyl group from 10- formyltetrahydrofolate to 5-phospho-ribosyl-glycinamide (GAR), producing 5-phospho-ribosyl-N-formylglycinamide (FGAR) and tetrahydrofolate.
  
 
 0.935
purT
Phosphoribosylglycinamide formyltransferase 2; Involved in the de novo purine biosynthesis. Catalyzes the transfer of formate to 5-phospho-ribosyl-glycinamide (GAR), producing 5-phospho-ribosyl-N-formylglycinamide (FGAR). Formate is provided by PurU via hydrolysis of 10-formyl-tetrahydrofolate; Belongs to the PurK/PurT family.
    
 0.906
yigB
Putative hydrolase of the HAD superfamily; Similar to E. coli putative phosphatase (AAC76815.1); Blastp hit to AAC76815.1 (238 aa), 87% identity in aa 1 - 238.
     
 0.768
yqiK
Similar to E. coli putative membrane protein (AAC76087.1); Blastp hit to AAC76087.1 (553 aa), 92% identity in aa 1 - 553.
      
 0.762
plsB
Glycerolphosphate acyltransferase activity; Similar to E. coli glycerol-3-phosphate acyltransferase (AAC77011.1); Blastp hit to AAC77011.1 (827 aa), 94% identity in aa 21 - 826; Belongs to the GPAT/DAPAT family.
      
 0.687
glpG
Protein of glp regulon; Rhomboid-type serine protease that catalyzes intramembrane proteolysis.
  
    0.627
idnO
5-keto-D-gluconate-5-reductase; Similar to E. coli 5-keto-D-gluconate 5-reductase (AAC77223.1); Blastp hit to AAC77223.1 (254 aa), 92% identity in aa 1 - 254; Belongs to the short-chain dehydrogenases/reductases (SDR) family.
      
 0.592
ygfE
Putative cytoplasmic protein; Activator of cell division through the inhibition of FtsZ GTPase activity, therefore promoting FtsZ assembly into bundles of protofilaments necessary for the formation of the division Z ring. It is recruited early at mid-cell but it is not essential for cell division.
     
 0.566
pheT
Phenylalanine tRNA synthetase, beta-subunit; phenylalanyl-tRNA synthetase beta chain. (SW:SYFB_SALTY); Belongs to the phenylalanyl-tRNA synthetase beta subunit family. Type 1 subfamily.
