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

mazGPutative pyrophosphatase; Similar to E. coli orf, hypothetical protein (AAC75823.1); Blastp hit to AAC75823.1 (263 aa), 93% identity in aa 2 - 263. (266 aa)    
Predicted Functional Partners:
relA
(p)ppGpp synthetase I; 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.
 
 0.979
dcd
dUTPase; Catalyzes the deamination of dCTP to dUTP.
     
 0.977
pyrG
CTP synthetase; Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as the source of nitrogen. Regulates intracellular CTP levels through interactions with the four ribonucleotide triphosphates.
    
 0.953
hpt
Hypoxanthine phosphoribosyltransferase; Acts preferentially on hypoxanthine; has very low activity towards guanine. Inactive towards xanthine (By similarity). Belongs to the purine/pyrimidine phosphoribosyltransferase family.
 
  
  0.922
pncB
Nicotinate phosphoribosyltransferase; Catalyzes the synthesis of beta-nicotinate D-ribonucleotide from nicotinate and 5-phospho-D-ribose 1-phosphate at the expense of ATP.
     
 0.919
icc
Cyclic 3',5'-adenosine monophosphate phosphodiesterase; Hydrolyzes cAMP to 5'-AMP. Plays an important regulatory role in modulating the intracellular concentration of cAMP, thereby influencing cAMP-dependent processes.
  
  
  0.918
nadR
Trifunctional protein; This enzyme has three activities: DNA binding, nicotinamide mononucleotide (NMN) adenylyltransferase and ribosylnicotinamide (RN) kinase. The DNA-binding domain binds to the nadB operator sequence in an NAD- and ATP-dependent manner. As NAD levels increase within the cell, the affinity of NadR for the nadB operator regions of nadA, nadB, and pncB increases, repressing the transcription of these genes. The RN kinase activity catalyzes the phosphorylation of RN to form nicotinamide ribonucleotide. The NMN adenylyltransferase activity catalyzes the transfer of the A [...]

spoT
(p)ppGpp synthetase II; 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.
  
 
 0.915
STM4104
Putative 5'-nucleotidase; Related esterase; similar to E. coli UDP-sugar hydrolase (5'-nucleotidase) (AAC73582.1); Blastp hit to AAC73582.1 (550 aa), 25% identity in aa 34 - 253, 28% identity in aa 383 - 506; 2',3'-cyclic phosphodiesterase; Belongs to the 5'-nucleotidase family.
 
  
  0.913
yjaD
Putative NTP pyrophosphohydrolases containing a Zn-finger; Probably nucleic-acid-binding; NADH pyrophosphatase. (SW:NUDC_SALTY).
