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

mngRTranscriptional repressor for the mannosyl-D-glycerate catabolic operon; Represses mngA and mngB. Regulates its own expression. (240 aa)    
Predicted Functional Partners:
nadR
Trifunctional NAD biosynthesis/regulator protein NadR; This enzyme has three activities: DNA binding, nicotinamide mononucleotide (NMN) adenylyltransferase and ribosylnicotinamide (RN) kinase. The DNA-binding domain binds to the nadB operator sequence in an NAD- and ATP-dependent manner. As NAD levels increase within the cell, the affinity of NadR for the nadB operator regions of nadA, nadB, and pncB increases, repressing the transcription of these genes. The RN kinase activity catalyzes the phosphorylation of RN to form nicotinamide ribonucleotide. The NMN adenylyltransferase activity [...]

mngA
Fused 2-O-a-mannosyl-D-glycerate specific PTS enzymes: IIA component/IIB component/IIC component; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. This system is involved in mannosyl- D-glycerate transport. Also involved in thermoinduction of ompC.
  
  
 0.781
mngB
Alpha-mannosidase; May hydrolyze 6-phospho-mannosyl-D-glycerate to mannose-6- phosphate and glycerate; Belongs to the glycosyl hydrolase 38 family.
 
  
 0.727
pdhR
Pyruvate dehydrogenase complex repressor; Transcriptional repressor for the pyruvate dehydrogenase complex genes aceEF and lpd.
  
    0.694
nanR
Sialic acid-inducible nan operon repressor; Transcriptional repressor that controls expression of the genes required for the catabolism of sialic acids. Represses expression of the nanATEK- yhcH, nanCMS and yjhBC operons. Acts by binding directly to the Nan box, a region of approximately 30 bp covering the promoter region.
  
  
 0.684
exuR
Hexuronate regulon transcriptional repressor; Repressor for the exu regulon that encode genes involved in hexuronate utilization. It regulates the ExuT, UxaCA and UxuRAB operons. Binds D-tagaturonate and D-fructuronate as inducers.
  
  
 0.632
dgoR
D-galactonate catabolism operon transcriptional repressor; Repressor for the dgoRKAT operon. Binds D-galactonate as an inducer.
  
  
 0.628
glcC
Glycolate-inducible glc operon transcriptional repressor; Transcriptional activator of the glcDEFGB operon which is associated with glycolate utilization, and encodes malate synthase G and the genes needed for glycolate oxidase activity. Also negatively regulates the transcription of its own gene. Glycolate acts as an effector, but GlcC can also use acetate as an alternative effector.
  
  
 0.596
gntR
D-gluconate inducible gluconate regulon transcriptional repressor; Negative regulator for the gluconate utilization system GNT- I, the gntUKR operon.
  
   
 0.552
phnD
Phosphonates-binding periplasmic protein; Phosphonate binding protein that is part of the phosphonate uptake system. Exhibits high affinity for 2-aminoethylphosphonate, and somewhat less affinity to ethylphosphonate, methylphosphonate, phosphonoacetate and phenylphosphonate.
