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. (224 aa)    
Predicted Functional Partners:
purP
5-formaminoimidazole-4-carboxamide-1-(beta)-D- ribofuranosyl 5'-monophosphate synthetase; 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.
    
 0.937
guaB
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.
 
  
 0.931
gch3
GTP cyclohydrolase III; Catalyzes the formation of 2-amino-5-formylamino-6- ribofuranosylamino-4(3H)-pyrimidinone ribonucleotide monophosphate and inorganic phosphate from GTP. Also has an independent pyrophosphate phosphohydrolase activity; Belongs to the archaeal-type GTP cyclohydrolase family.
 
     0.924
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.
     
 0.904
ADZ10737.1
PfkB domain protein; PFAM: Carbohydrate/purine kinase; KEGG: mth:MTH1544 ribokinase; Belongs to the carbohydrate kinase PfkB family.
    
  0.901
surE
Multifunctional protein surE; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
     
  0.900
ADZ10646.1
PFAM: Biopolymer transport protein ExbD/TolR; KEGG: mmg:MTBMA_c14030 hypothetical protein.
       0.882
cofE
F420-0:gamma-glutamyl 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.
       0.851
cofD
LPPG:FO 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.
 
     0.817
ADZ10645.1
PFAM: MotA/TolQ/ExbB proton channel; KEGG: mmg:MTBMA_c14040 biopolymer transport protein.
