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.

relQ(p)ppGpp synthetase; Functions as a (p)ppGpp synthase; GDP can be used instead of GTP, resulting in an increase of (p)ppGpp synthesis. Overexpression in relA mutants (triple relA-yjbM-ywaC deletions and single relA deletions) leads to growth arrest; GTP levels fall drastically, various guanine-related nucleotides are synthesized (ppGp or pGpp), the cellular transcriptional profile changes dramatically and 70S ribosome dimerization occurs. Overexpression in the presence of a wild-type relA gene does not have these effects. In eubacteria ppGpp (guanosine 3'-diphosphate 5-' diphosphate) i [...] (210 aa)    
Predicted Functional Partners:
rsh
GTP pyrophosphokinase (RelA/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 formation of pppGpp which is then hydrolyzed to form ppGpp, it is probably the hydrolysis activity that is required for optimal growth (Probable); Belongs to the RelA/SpoT family.

relP
(p)ppGpp synthetase; Functions as a (p)ppGpp synthase; GDP can be used instead of GTP, resulting in an increase of (p)ppGpp synthesis. The enzyme binds ATP, then GDP or GTP and catalysis is highly cooperative. 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. Probably has a minor role in the stringent response ; Belongs to the RelA/SpoT family.

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.

folEB
GTP cyclohydrolase I; Converts GTP to 7,8-dihydroneopterin triphosphate. Belongs to the GTP cyclohydrolase IV family.

folEA
GTP cyclohydrolase I; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the GTP cyclohydrolase I family.

moaA
Molybdenum cofactor biosynthesis protein A; Catalyzes the cyclization of GTP to (8S)-3',8-cyclo-7,8- dihydroguanosine 5'-triphosphate (By similarity). Required for both nitrate assimilation and respiration.
   
 
  0.801
ribAB
Fused GTP cyclohydrolase II and 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.

mnmE
tRNA modification GTPase and tRNA-U34 5-formylation enzyme; Exhibits a very high intrinsic GTPase hydrolysis rate. Involved in the addition of a carboxymethylaminomethyl (cmnm) group at the wobble position (U34) of certain tRNAs, forming tRNA- cmnm(5)s(2)U34.
   
    0.735
codY
Transcriptional regulator, GTP and BCAA-dependent; DNA-binding protein that represses the expression of many genes that are induced as cells make the transition from rapid exponential growth to stationary phase and sporulation. It is a GTP- binding protein that senses the intracellular GTP concentration as an indicator of nutritional limitations. At low GTP concentration it no longer binds GTP and stop to act as a transcriptional repressor.

trmF
tRNA uridine 5-carboxymethylaminomethyl modification enzyme; NAD-binding protein involved in the addition of a carboxymethylaminomethyl (cmnm) group at the wobble position (U34) of certain tRNAs, forming tRNA-cmnm(5)s(2)U34; Belongs to the MnmG family.
