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

mazGTranscriptional 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. (324 aa)    
Predicted Functional Partners:
mfd
Transcription-repair coupling factor; Couples transcription and DNA repair by recognizing RNA polymerase (RNAP) stalled at DNA lesions. Mediates ATP-dependent release of RNAP and its truncated transcript from the DNA, and recruitment of nucleotide excision repair machinery to the damaged site; In the C-terminal section; belongs to the helicase family. RecG subfamily.

hpt
Hypoxanthine phosphoribosyltransferase; Identified by match to protein family HMM PF00156; match to protein family HMM TIGR01203; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
 
 
  0.924
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.
 
  
 0.922
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.
  
 
 0.911
surE
Acid phosphatase SurE; Identified by match to protein family HMM PF01975; match to protein family HMM TIGR00087.
  
 
 0.911
ABK74721.1
Identified by match to protein family HMM PF00478; match to protein family HMM PF00571; match to protein family HMM TIGR01303.
  
 
 0.909
ABK75325.1
Identified by match to protein family HMM PF00478; match to protein family HMM TIGR01304; Belongs to the IMPDH/GMPR family.
  
 
 0.907
guaA
Glutamine-hydrolyzing GMP synthase; Catalyzes the synthesis of GMP from XMP.
  
 
  0.905
ndk
Nucleoside diphosphate kinase; Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate; Belongs to the NDK family.
   
 
  0.901
ABK72606.1
Transcriptional regulator, TetR family protein; Identified by match to protein family HMM PF00440.
