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

mazGmazG protein (mazG); Involved in the regulation of bacterial cell survival under conditions of nutritional stress. Regulates the MazE-MazF toxin- antitoxin (TA) system that mediates programmed cell death (PCD). This is achieved by lowering the cellular concentration of (p)ppGpp produced by RelA under amino acid starvation, thus protecting the cell from the toxicity of MazF. Reduction of (p)ppGpp can be achieved by direct degradation of (p)ppGpp or by degradation of NTPs, which are substrates for (p)ppGpp synthesis by RelA (By similarity); Belongs to the nucleoside triphosphate pyrophos [...] (263 aa)    
Predicted Functional Partners:
pyrR
Pyrimidine operon regulatory protein (pyrR); Regulates the transcription of the pyrimidine nucleotide (pyr) operon in response to exogenous pyrimidines.
 
  
  0.808
dcd
Deoxycytidine triphosphate deaminase (dcd); Catalyzes the deamination of dCTP to dUTP.
     
 0.792
nrdD
Anaerobic ribonucleoside-triphosphate reductase (nrdD); Catalyzes the conversion of ribonucleotides into deoxyribonucleotides, which are required for DNA synthesis and repair. Belongs to the anaerobic ribonucleoside-triphosphate reductase family.
     
  0.769
ndk
Nucleoside diphosphate kinase (ndk); 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.
     
  0.769
nadR
Transcriptional regulator (nadR); This enzyme has two activities: nicotinamide mononucleotide (NMN) adenylyltransferase and ribosylnicotinamide (RN) kinase. The RN kinase activity catalyzes the phosphorylation of RN to form nicotinamide ribonucleotide. The NMN adenylyltransferase activity catalyzes the transfer of the AMP moiety of ATP to nicotinamide ribonucleotide to form NAD(+); In the C-terminal section; belongs to the bacterial RNK family.
     
 0.734
relA
GTP pyrophosphokinase (relA); In eubacteria ppGpp (guanosine 3'-diphosphate 5-' diphosphate) is a mediator of the stringent response that coordinates a variety of cellular activities in response to changes in nutritional abundance. This enzyme catalyzes the formation of pppGpp which is then hydrolyzed to form ppGpp (By similarity).
  
 
 0.715
guaA
GMP synthase (guaA); Catalyzes the synthesis of GMP from XMP.
    
  0.701
glpK
Glycerol kinase (glpK); Key enzyme in the regulation of glycerol uptake and metabolism. Catalyzes the phosphorylation of glycerol to yield sn- glycerol 3-phosphate; Belongs to the FGGY kinase family.
 
      0.651
cpdA
lacZ expression regulator (icc); Hydrolyzes cAMP to 5'-AMP. Plays an important regulatory role in modulating the intracellular concentration of cAMP, thereby influencing cAMP-dependent processes. May coordinate responses to nutritional stress, ensuring optimal competence development. Belongs to the cAMP phosphodiesterase class-III family.
  
  
  0.633
amiB
N-acetylmuramoyl-L-alanine amidase, putative; Cell-wall hydrolase involved in septum cleavage during cell division; Belongs to the N-acetylmuramoyl-L-alanine amidase 3 family.
