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

folDMethylenetetrahydrofolate dehydrogenase/methenyltetrahydrofolate cyclohydrolase (folD); Catalyzes the oxidation of 5,10-methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10- methenyltetrahydrofolate to 10-formyltetrahydrofolate. (282 aa)    
Predicted Functional Partners:
purN
Phosphoribosylglycinamide formyltransferase (purN); 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.
 
 
 0.925
fmt
methionyl-tRNA formyltransferase (fmt); 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.
 
 
 0.909
glyA
Serine hydroxymethyltransferase (serine methylase) (glyA); 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.
 
 0.901
HI_0858
Conserved hypothetical 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) (By similarity).

purH
Phosphoribosylaminoimidazolecarboxamide formyltransferase (purH); Similar to SP:P15639 GB:J05126 GB:X51950 PID:147420 PID:396345 percent identity: 77.19; identified by sequence similarity; putative.
 
 
 0.864
purU
Formyltetrahydrofolate deformylase (purU); Catalyzes the hydrolysis of 10-formyltetrahydrofolate (formyl-FH4) to formate and tetrahydrofolate (FH4).
  
 
 0.856
purL
Phosphoribosylformylglycinamidine synthase (purL); Phosphoribosylformylglycinamidine synthase involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate.
  
  
 0.838
purD
Phosphoribosylamine--glycine ligase (purD); Similar to SP:P15640 GB:J05126 GB:X51950 PID:147421 PID:396344 percent identity: 75.18; identified by sequence similarity; putative.
  
 
 0.760
purB
Adenylosuccinate lyase (purB); Similar to GB:M74924 SP:P25739 PID:145203 PID:42585 GB:U00096 percent identity: 76.97; identified by sequence similarity; putative.
  
  
 0.742
def
Polypeptide deformylase (def); Removes the formyl group from the N-terminal Met of newly synthesized proteins. Requires at least a dipeptide for an efficient rate of reaction. N-terminal L-methionine is a prerequisite for activity but the enzyme has broad specificity at other positions (By similarity).
