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

guaBInosine-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. (513 aa)    
Predicted Functional Partners:
guaA
Glutamine-hydrolyzing GMP synthase; Catalyzes the synthesis of GMP from XMP.
 
 0.999
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.
 
 
 0.994
ABK75325.1
Identified by match to protein family HMM PF00478; match to protein family HMM TIGR01304; Belongs to the IMPDH/GMPR family.
  
 
0.988
purH
Bifunctional purine biosynthesis protein PurH; Identified by match to protein family HMM PF01808; match to protein family HMM PF02142; match to protein family HMM TIGR00355.
 
 
 0.974
hpt
Hypoxanthine phosphoribosyltransferase; Identified by match to protein family HMM PF00156; match to protein family HMM TIGR01203; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 
 0.964
ABK74721.1
Identified by match to protein family HMM PF00478; match to protein family HMM PF00571; match to protein family HMM TIGR01303.
 
 
0.951
rdgB
Non-canonical purine NTP pyrophosphatase, RdgB/HAM1 family protein; Pyrophosphatase that catalyzes the hydrolysis of nucleoside triphosphates to their monophosphate derivatives, with a high preference for the non-canonical purine nucleotides XTP (xanthosine triphosphate), dITP (deoxyinosine triphosphate) and ITP. Seems to function as a house-cleaning enzyme that removes non-canonical purine nucleotides from the nucleotide pool, thus preventing their incorporation into DNA/RNA and avoiding chromosomal lesions. Belongs to the HAM1 NTPase family.
 
 0.950
surE
Acid phosphatase SurE; Identified by match to protein family HMM PF01975; match to protein family HMM TIGR00087.
  
 
 0.921
mazG
Transcriptional regulator, MazG family protein; Required to maintain the full capacity of the mycobacteria to respond to oxidative stress via the degradation of the oxidation- induced damaged nucleotides. It hydrolyzes all canonical (d)NTPs, as well as the mutagenic dUTP and 8-oxo-7,8-dihydro-2'-deoxyguanosine 5'- triphosphate (8-oxo-dGTP). Also involved in the transcriptional activation of RelA in response to oxidative stress.
  
 
 0.911
purF
Amidophosphoribosyltransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine.
 
 
 0.869
