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

purOIMP cyclohydrolase; Catalyzes the cyclization of 5-formylamidoimidazole-4- carboxamide ribonucleotide to IMP. (208 aa)    
Predicted Functional Partners:
purP
Hypothetical protein; Catalyzes the ATP- and formate-dependent formylation of 5- aminoimidazole-4-carboxamide-1-beta-d-ribofuranosyl 5'-monophosphate (AICAR) to 5-formaminoimidazole-4-carboxamide-1-beta-d-ribofuranosyl 5'-monophosphate (FAICAR) in the absence of folates.
    
 0.986
guaB_1
Inosine-5'-monophosphate dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
    
 0.964
purA
Adenylosuccinate synthetase; Plays an important role in the de novo pathway of purine nucleotide biosynthesis. Catalyzes the first committed step in the biosynthesis of AMP from IMP; Belongs to the adenylosuccinate synthetase family.
     
 0.957
purD
Phosphoribosylamine--glycine ligase; Belongs to the GARS family.
  
 
 0.837
purL
Phosphoribosylformylglycinamidine synthase 2; Part of the phosphoribosylformylglycinamidine synthase complex involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate. The FGAM synthase complex is composed of three subunits. PurQ produces an ammonia molecule by converting glutamine to glutamate. PurL transfers the ammonia molecule to FGAR to form FGAM in an ATP- dependent manner. PurS interacts with PurQ and PurL and is thought to assist i [...]

KZX10203.1
Biopolymer transport protein ExbD/TolR.
       0.775
KZX10204.1
Flagellar motor protein MotA.
       0.757
cofD
2-phospho-L-lactate transferase; Catalyzes the transfer of the phosphoenolpyruvate moiety from enoylpyruvoyl-2-diphospho-5'-guanosine (EPPG) to 7,8-didemethyl-8- hydroxy-5-deazariboflavin (FO) with the formation of dehydro coenzyme F420-0 and GMP.
       0.743
fbiB_2
Coenzyme F420:L-glutamate ligase; Catalyzes the GTP-dependent successive addition of two or more gamma-linked L-glutamates to the L-lactyl phosphodiester of 7,8- didemethyl-8-hydroxy-5-deazariboflavin (F420-0) to form coenzyme F420- 0-glutamyl-glutamate (F420-2) or polyglutamated F420 derivatives.
       0.743
purF
Amidophosphoribosyltransferase precursor; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine.
