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.

cyaAAdenylate cyclase (cyaA); Plays an essential role in competence development. (843 aa)    
Predicted Functional Partners:
crp
Catabolite gene activator (crp); A global transcription regulator required for bacterial competence. Complexes with cyclic AMP (cAMP) which allosterically activates DNA binding (to consensus sequence 5'-AAATGTGATCTAGATCACATTT- 3') to regulate transcription at 54 promoters. There are 2 consensus subclasses; CRP-N (above) and CRP-S (T6 changed to C and A17 changed to G) which obligatorily also requires Sxy for expression. CRP-S sites bind DNA but do not activate transcription in the absence of Sxy. Probably induces a severe bend in DNA. Probably acts as a negative regulator of its own sy [...]

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.
  
  
 0.935
mazG
mazG 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 [...]

ribA
GTP cyclohydrolase II (ribA); Catalyzes the conversion of GTP to 2,5-diamino-6- ribosylamino-4(3H)-pyrimidinone 5'-phosphate (DARP), formate and pyrophosphate; Belongs to the GTP cyclohydrolase II family.
     
  0.920
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).
     
  0.920
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.
     
  0.920
folE
GTP cyclohydrolase I (folE); Similar to GB:U00007 SP:P27511 GB:X63910 PID:312964 PID:405902 percent identity: 63.93; identified by sequence similarity; putative.
     
  0.920
moaA
Molybdenum cofactor biosynthesis protein A (moaA); Catalyzes the cyclization of GTP to (8S)-3',8-cyclo-7,8- dihydroguanosine 5'-triphosphate.
     
  0.920
spoT
Guanosine-3',5'-bis(diphosphate) 3'- pyrophosphohydrolase (spoT); 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 degradation of ppGpp into GDP. It may also be capable of catalyzing the synthesis of ppGpp (By similarity); Belongs to the RelA/SpoT family.
     
  0.920
hemY
hemY protein (hemY); Involved in a late step of protoheme IX synthesis.
