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

ptsPGeneral PTS system enzyme I, transcriptional regulator with NPR and NTR proteins; Component of the phosphoenolpyruvate-dependent nitrogen- metabolic phosphotransferase system (nitrogen-metabolic PTS), that seems to be involved in regulating nitrogen metabolism. Enzyme I-Ntr transfers the phosphoryl group from phosphoenolpyruvate (PEP) to the phosphoryl carrier protein (NPr). Could function in the transcriptional regulation of sigma-54 dependent operons in conjunction with the NPr (PtsO) and EIIA-Ntr (PtsN) proteins. Enzyme I-Ntr is specific for NPr. (748 aa)    
Predicted Functional Partners:
ptsO
Phosphocarrier protein HPr-like NPr; Nitrogen related; exchanges phosphate with Enzyme I; similar to E. coli phosphocarrier protein HPr-like NPr, nitrogen related, exchanges phosphate with Enzyme I, Hpr (AAC76238.1); Blastp hit to AAC76238.1 (90 aa), 96% identity in aa 1 - 90.

fruF
Phosphoenolpyruvate-dependent sugar phosphotransferase system, EIIA 2; 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. The enzyme II FruAB PTS system is involved in fructose transport.

STM3256
Putative phosphotransferase system mannitol/fructose-specific IIA domain protein; Similar to E. coli PTS system, fructose-specific IIA/fpr component (AAC75230.1); Blastp hit to AAC75230.1 (376 aa), 52% identity in aa 3 - 141, 41% identity in aa 197 - 374.
 
 
 
 0.964
crr
Glucose-specific IIA 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. The enzyme II complex composed of PtsG and Crr is involved in glucose transport. It can also phosphorylate mannose, methyl alpha-glucoside and 2-deoxy-glucose. The non-phosphorylated EIII-Glc is an inhibitor for uptake of certain sugars such as maltose, melibiose, lactose, and glycerol. Phosphorylated EIII-Glc [...]

ptsN
Sugar specific PTS family enzyme IIA; Also regulates N metabolism; similar to E. coli phosphotransferase system enzyme IIA, regulates N metabolism (AAC76236.1); Blastp hit to AAC76236.1 (163 aa), 95% identity in aa 1 - 163.
  
  
 0.936
ptsH
Phosphohistidinoprotein-hexose phosphotransferase; General (non sugar-specific) component of the phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS). This major carbohydrate active-transport system catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. The phosphoryl group from phosphoenolpyruvate (PEP) is transferred to the phosphoryl carrier protein HPr by enzyme I. Phospho-HPr then transfers it to the PTS EIIA domain.
 
 
 
 0.885
ygdP
Putative invasion protein; Accelerates the degradation of transcripts by removing pyrophosphate from the 5'-end of triphosphorylated RNA, leading to a more labile monophosphorylated state that can stimulate subsequent ribonuclease cleavage; Belongs to the Nudix hydrolase family. RppH subfamily.

fruA
Fructose-specific transport protein; Sugar Specific PTS system; similar to E. coli PTS system, fructose-specific transport protein (AAC75228.1); Blastp hit to AAC75228.1 (563 aa), 92% identity in aa 1 - 563.
      
 0.768
STM3779
Putative phosphotransferase system; HPr-related protein; similar to E. coli PTS system protein HPr (AAC75468.1); Blastp hit to AAC75468.1 (85 aa), 28% identity in aa 1 - 83.
  
 
 
 0.754
ptsA
General PTS family enzyme I; Similar to E. coli PEP-protein phosphotransferase system enzyme I (AAC76929.1); Blastp hit to AAC76929.1 (711 aa), 90% identity in aa 1 - 711.
