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

gcvTGlycine cleavage complex protein T; The glycine cleavage system catalyzes the degradation of glycine. (364 aa)    
Predicted Functional Partners:
gcvP
Glycine cleavage complex protein P; The glycine cleavage system catalyzes the degradation of glycine. The P protein binds the alpha-amino group of glycine through its pyridoxal phosphate cofactor; CO(2) is released and the remaining methylamine moiety is then transferred to the lipoamide cofactor of the H protein; Belongs to the GcvP family.
 0.999
gcvH
Glycine cleavage complex protein H; 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.
 0.999
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 (By similarity).
 
 0.998
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.
  
 
 0.974
purH
Phosphoribosylaminoimidazolecarboxamide formyltransferase; Bifunctional; bifunctional purine biosynthesis protein PURH. (SW:PUR9_SALTY); IMP cyclohydrolase.
   
 
 0.959
metH
B12-dependent homocysteine-N5-methyltetrahydrofolate transmethylase; 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 (By similarity).
  
 
 0.958
lpdA
Lipoamide dehydrogenase (NADH); Component of 2-oxodehydrogenase and pyruvate complexes; L protein of glycine cleavage complex second part; similar to E. coli lipoamide dehydrogenase (NADH); component of 2-oxodehydrogenase and pyruvate complexes; L-protein of glycine cleavage complex (AAC73227.1); Blastp hit to AAC73227.1 (474 aa), 98% identity in aa 1 - 474.
 
 0.956
metF
5,10-methylenetetrahydrofolate reductase. (SW:METF_SALTY); Belongs to the methylenetetrahydrofolate reductase family.
  
 
 0.956
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.
   
 
 0.939
thyA
Thymidylate synthetase; 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 reductant in the reaction, yielding dihydrofolate (DHF) as a by- product. This enzymatic reaction provides an intracellular de novo source of dTMP, an essential precursor for DNA biosynthesis.
