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

fhsFormyltetrahydrofolate synthetase; Similar to Staphylococcus aureus (strain N315) formyltetrahydrofolate synthetase Fhs or SA1553 or SAV1732 SWALL:Q99TD2 (EMBL:AP003134) (555 aa) fasta scores: E(): 1.2e-125, 59.34% id in 551 aa, and to Moorella thermoacetica formate--tetrahydrofolate ligase Fhs SWALL:FTHS_MOOTH (SWALL:P21164) (559 aa) fasta scores: E(): 4.9e-116, 55.57% id in 556 aa. (550 aa)    
Predicted Functional Partners:
folD
Methylenetetrahydrofolate dehydrogenase; Catalyzes the oxidation of 5,10-methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10- methenyltetrahydrofolate to 10-formyltetrahydrofolate.

purH
Similar to Mycobacterium tuberculosis bifunctional purine biosynthesis protein PurH [includes: phosphoribosylaminoimidazolecarboxamide formyltransferase (EC 2.1.2.3); IMP cyclohydorlase (EC 3.5.4.10)] or Rv0957 or MT0984 or MTCY10D7.17c SW:PUR9_MYCTU (P71553) (523 aa) fasta scores: E(): 1e-137, 68.06% id in 526 aa, and to Escherichia coli bifunctional purine biosynthesis protein [includes: phosphoribosylaminoimidazolecarboxamide formyltransferase (EC 2.1.2.3); IMP cyclohydrolase (EC 3.5.4.10)] PurH or B4006 SW:PUR9_ECOLI (P15639) (529 aa) fasta scores: E(): 1e-58, 45.25% id in 537 aa.
  
 0.979
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.
  
 0.972
metH
5-methyltetrahydrofolate--homocysteine methyltransferase; Catalyzes the transfer of a methyl group from methyl- cobalamin to homocysteine, yielding enzyme-bound cob(I)alamin and methionine. Subsequently, remethylates the cofactor using methyltetrahydrofolate.
  
 
 0.963
purN
5'-phosphoribosylglycinamide formyltransferase; 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.

thyX
Conserved hypothetical protein; Catalyzes the reductive methylation of 2'-deoxyuridine-5'- monophosphate (dUMP) to 2'-deoxythymidine-5'-monophosphate (dTMP) while utilizing 5,10-methylenetetrahydrofolate (mTHF) as the methyl donor, and NADPH and FADH(2) as the reductant.
