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

nnrBifunctional NAD(P)H-hydrate repair enzyme; Bifunctional enzyme that catalyzes the epimerization of the S- and R-forms of NAD(P)HX and the dehydration of the S-form of NAD(P)HX at the expense of ADP, which is converted to AMP. This allows the repair of both epimers of NAD(P)HX, a damaged form of NAD(P)H that is a result of enzymatic or heat-dependent hydration. In the N-terminal section; belongs to the NnrE/AIBP family. (515 aa)    
Predicted Functional Partners:
tsaE
tRNA(ANN) t(6)A37 threonylcarbamoyladenosine modification protein; Required for the formation of a threonylcarbamoyl group on adenosine at position 37 (t(6)A37) in tRNAs that read codons beginning with adenine. Is probably involved in the transfer of the threonylcarbamoyl moiety of threonylcarbamoyl-AMP (TC-AMP) to the N6 group of A37, together with TsaD and TsaB. TsaE seems to play an indirect role in the t(6)A biosynthesis pathway, possibly in regulating the core enzymatic function of TsaD. Displays ATPase activity in vitro.

nuoC
NADH:ubiquinone oxidoreductase, fused CD subunit; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient; In the C-terminal section; belongs to the complex I 49 kDa subunit family.

miaA
Delta(2)-isopentenylpyrophosphate tRNA-adenosine transferase; Catalyzes the transfer of a dimethylallyl group onto the adenine at position 37 in tRNAs that read codons beginning with uridine, leading to the formation of N6-(dimethylallyl)adenosine (i(6)A); Belongs to the IPP transferase family.
  
  
 0.874
amiB
N-acetylmuramoyl-l-alanine amidase II; Cell-wall hydrolase involved in septum cleavage during cell division. Can also act as powerful autolysin in the presence of murein synthesis inhibitors.
  
  
 0.872
mutL
Methyl-directed mismatch repair protein; This protein is involved in the repair of mismatches in DNA. It is required for dam-dependent methyl-directed DNA mismatch repair. May act as a 'molecular matchmaker', a protein that promotes the formation of a stable complex between two or more DNA-binding proteins in an ATP-dependent manner without itself being part of the final effector complex. The ATPase activity of MutL is stimulated by DNA.
 
  
 0.853
nudE
Adenosine nucleotide hydrolase; Active on adenosine(5')triphospho(5')adenosine (Ap3A), ADP- ribose, NADH, adenosine(5')diphospho(5')adenosine (Ap2A); Belongs to the Nudix hydrolase family.
 
 0.803
rlmB
23S rRNA mG2251 2'-O-ribose methyltransferase, SAM-dependent; Specifically methylates the ribose of guanosine 2251 in 23S rRNA.
   
 
 0.785
nudF
ADP-ribose pyrophosphatase; Acts on ADP-mannose and ADP-glucose as well as ADP-ribose. Prevents glycogen biosynthesis. The reaction catalyzed by this enzyme is a limiting step of the gluconeogenic process. Belongs to the Nudix hydrolase family. NudF subfamily.
  
 0.776
hflX
GTPase, stimulated by 50S subunit binding; GTPase that associates with the 50S ribosomal subunit and may have a role during protein synthesis or ribosome biogenesis. In vitro, also exhibits ATPase activity.
     
 0.775
nudB
Dihydroneopterin triphosphate pyrophosphatase; Catalyzes the hydrolysis of dihydroneopterin triphosphate to dihydroneopterin monophosphate and pyrophosphate. Required for efficient folate biosynthesis. Can also hydrolyze nucleoside triphosphates with a preference for dATP.
