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

fhs_1Formate--tetrahydrofolate ligase; Identified by match to protein family HMM PF01268; Belongs to the formate--tetrahydrofolate ligase family. (556 aa)    
Predicted Functional Partners:
folD
Tetrahydrofolate dehydrogenase/cyclohydrolase, NAD(P)-binding domain protein; Catalyzes the oxidation of 5,10-methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10- methenyltetrahydrofolate to 10-formyltetrahydrofolate.
 
 
 0.989
glyA
Glycine hydroxymethyltransferase; Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism.
  
 0.876
fchA
Putative methenyltetrahydrofolate cyclohydrolase; Identified by match to protein family HMM PF04961.
    
 0.746
folA
Dihydrofolate reductase; Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis.
  
 
 0.729
ftcD
Glutamate formimidoyltransferase; Identified by match to protein family HMM PF02971; match to protein family HMM PF07837; match to protein family HMM TIGR02024.
    
  0.709
fhs_2
Formate--tetrahydrofolate ligase; Identified by match to protein family HMM PF01268; Belongs to the formate--tetrahydrofolate ligase family.
  
  
 
0.700
coaC
Phosphopantothenoylcysteine decarboxylase; Identified by match to protein family HMM PF02441; match to protein family HMM TIGR02113.
    
 0.647
guaA
GMP synthase (glutamine-hydrolyzing), C-terminal domain protein; Catalyzes the synthesis of GMP from XMP.
   
  
 0.645
coaB
Phosphopantothenate--cysteine ligase; Identified by match to protein family HMM PF04127; match to protein family HMM TIGR02114.
    
 0.621
sun
Ribosomal RNA small subunit methyltransferase B; Specifically methylates the cytosine at position 967 (m5C967) of 16S rRNA.
  
 0.613
