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

fau5-formyltetrahydrofolate cyclo-ligase family protein; Involved in the removal of 5-formyltetrahydrofolate. In vitro, it is a potent inhibitor of various folate-dependent enzymes in the C1 metabolism network and in vivo it might function as a folate storage. 5-formyltetrahydrofolate is also used as an antifolate rescue agent in cancer chemotherapy. Catalyzes the irreversible ATP-dependent transformation of 5-formyltetrahydrofolate (5-CHO-THF) to form 5,10- methenyltetrahydrofolate (5,10-CH=THF). The reverse reaction is catalyzed by the serine hydroxymethyltransferase GlyA (SHMT). (182 aa)    
Predicted Functional Partners:
folD
Methenyltetrahydrofolate cyclohydrolase; Catalyzes the oxidation of 5,10-methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10- methenyltetrahydrofolate to 10-formyltetrahydrofolate. This enzyme is specific for NADP.
 
  
 0.976
purN
Phosphoribosylglycinamide formyltransferase 1; 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; Belongs to the GART family.
  
 
 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. PurT is also able to cleave acetyl phosphate and carbamoyl phosphate to produce ATP with acetate and carbamate, respectively; Belongs to the PurK/PurT family.
    
 0.905
glyA
Serine 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. Thus, is able to catalyze the cleavage of allothreonine and 3-phenylserine. Also catalyzes the irreversible conversion of 5,10-m [...]
  
 
 0.834
glpG
Rhomboid protease GlpG; Rhomboid-type serine protease that catalyzes intramembrane proteolysis.
  
    0.585
zapA
FtsZ stabilizer; 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; Belongs to the ZapA family. Type 1 subfamily.
  
  
 0.571
folC
Bifunctional folylpolyglutamate synthase/ dihydrofolate synthase; Functions in two distinct reactions of the de novo folate biosynthetic pathway. Catalyzes the addition of a glutamate residue to dihydropteroate (7,8-dihydropteroate or H2Pte) to form dihydrofolate (7,8-dihydrofolate monoglutamate or H2Pte-Glu). Also catalyzes successive additions of L-glutamate to tetrahydrofolate or 10- formyltetrahydrofolate or 5,10-methylenetetrahydrofolate, leading to folylpolyglutamate derivatives.
 
  
 0.568
gcvH
Glycine cleavage complex lipoylprotein; The glycine cleavage system catalyzes the degradation of glycine. The H protein shuttles the methylamine group of glycine from the P protein to the T protein.
  
  
 0.561
fmt
10-formyltetrahydrofolate:L-methionyl-tRNA(fMet) N-formyltransferase; Attaches a formyl group to the free amino group of methionyl- tRNA(fMet). The formyl group appears to play a dual role in the initiator identity of N-formylmethionyl-tRNA by promoting its recognition by IF2 and preventing the misappropriation of this tRNA by the elongation apparatus. Belongs to the Fmt family.
  
  
 0.545
yigB
5-amino-6-(5-phospho-D-ribitylamino)uracil phosphatase; Catalyzes the dephosphorylation of 5-amino-6-(5-phospho-D- ribitylamino)uracil, and thus could be involved in the riboflavin biosynthesis pathway. Is also able to dephosphorylate flavin mononucleotide (FMN) and other phosphoric acid esters. YigB is important for the formation of dormant persister cells. Belongs to the HAD-like hydrolase superfamily.
