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.

SAG1940GTP pyrophosphokinase family protein; 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. (738 aa)    
Predicted Functional Partners:
SAG1095
GTP pyrophosphokinase family protein; Similar to OMNI:NTL01SPL0878; identified by sequence similarity; putative.
    
 0.959
SAG1329
GTP pyrophosphokinase family protein; Similar to OMNI:NTL01SPL0666; identified by sequence similarity; putative.
    
 0.959
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.
    
 0.957
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.928
ribA
Riboflavin biosynthesis protein RibA; Catalyzes the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate; In the C-terminal section; belongs to the GTP cyclohydrolase II family.
    
 0.922
nrdD
Anaerobic ribonucleoside-triphosphate reductase; Identified by match to PFAM protein family HMM PF01228.
     
 0.914
rpsM
Ribosomal protein S13; Located at the top of the head of the 30S subunit, it contacts several helices of the 16S rRNA. In the 70S ribosome it contacts the 23S rRNA (bridge B1a) and protein L5 of the 50S subunit (bridge B1b), connecting the 2 subunits; these bridges are implicated in subunit movement. Contacts the tRNAs in the A and P-sites. Belongs to the universal ribosomal protein uS13 family.
   
  0.907
nrdF-1
Ribonucleoside-diphosphate reductase 2, beta subunit; Identified by match to PFAM protein family HMM PF00268.
   
 
  0.906
nrdE-1
Ribonucleoside-diphosphate reductase 2, alpha subunit; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides.
   
 
  0.906
nrdF-2
Ribonucleoside-diphosphate reductase 2, beta subunit; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides; Belongs to the ribonucleoside diphosphate reductase small chain family.
