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.

TM_0729(p)ppGpp synthetase; 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. (751 aa)    
Predicted Functional Partners:
ribBA
GTP cyclohydrolase II/3,4-dihydroxy-2-butanone 4-phosphate synthase; Catalyzes the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate; In the N-terminal section; belongs to the DHBP synthase family.
  
 
 0.975
TM_0195
Guanosine pentaphosphate phosphohydrolase, putative; Similar to GB:AE000511 PID:2313368 percent identity: 49.63; identified by sequence similarity; putative.
  
 
 0.970
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.968
mazG
mazG protein; Catalyzes the hydrolysis of all eight canonical ribonucleoside triphosphates (NTP) and deoxyribonucleoside triphosphates (dNTP) to their corresponding nucleoside monophosphates ((d)NMP) and PPi and subsequently hydrolyzes the resultant PPi to Pi. The NTPase activity with deoxyribonucleoside triphosphates as substrate is higher than corresponding ribonucleoside triphosphates. dGTP is the best substrate among the deoxyribonucleoside triphosphates, and GTP is the best among the ribonucleoside triphosphates.
  
 
 0.963
TM_0118
Ribonucleotide reductase, B12-dependent; Catalyzes the reduction of ribonucleotides to deoxyribonucleotides. May function to provide a pool of deoxyribonucleotide precursors for DNA repair during oxygen limitation and/or for immediate growth after restoration of oxygen.
   
 
  0.955
TM_0385
Conserved hypothetical protein; Similar to GB:Pyro_h percent identity: 52.27; identified by sequence similarity; putative.
     
 0.955
rplW
Ribosomal protein L23; One of the early assembly proteins it binds 23S rRNA. One of the proteins that surrounds the polypeptide exit tunnel on the outside of the ribosome. Forms the main docking site for trigger factor binding to the ribosome; Belongs to the universal ribosomal protein uL23 family.
  
 
   0.895
TM_0268
5-methyltetrahydrofolate S-homocysteine methyltransferase; Similar to GB:U00017 PID:466997 percent identity: 54.29; identified by sequence similarity; putative.
    
 0.889
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.
   
  0.885
rplX
Ribosomal protein L24; One of two assembly initiator proteins, it binds directly to the 5'-end of the 23S rRNA, where it nucleates assembly of the 50S subunit.
