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

ptsIPutative Phosphoenolpyruvate-protein 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. Enzyme I transfers the phosphoryl group from phosphoenolpyruvate (PEP) to the phosphoryl carrier protein (HPr). (576 aa)    
Predicted Functional Partners:
ptsH
Phosphocarrier protein HPr (Histidine-containing protein) (Protein H). This is a component of the phosphoenolpyruvate-dependent sugar phosphotransferase system (PTS), a major carbohydrate active -transport system. The phosphoryl group from phosphoenolpyruvate (PEP) is transferred to the phosphoryl carrier protein HPr by enzyme I. Phospho-HPr then transfers it to the permease (enzymes II/III). HPr is common to all PTS (By similarity). 64% HPr_HisP_S.IPR000032; HPr_protein.IPR002114; HPr_SerP_S. IPR005698; PTS_HPr. Pfam:PF00381; PTS-HPr; 1; High confidence in function and specificity.
 
 0.999
ptsL
This is a component of the phosphoenolpyruvate-dependent sugar phosphotransferase system (PTS), a major carbohydrate active -transport system. The IICD domains contain the sugar binding site and the transmembrane channel; the IIA domain contains the primary phosphorylation site (the donor is phospho-HPr); IIA transfers its phosphoryl group to the IIB domain which finally transfers it to the sugar. 32% EIIA-man.IPR004720; PTSIIB_sorb. Pfam:PF03610; EIIA-man; 1.PF03830; PTSIIB_sorb; 1; Specificity unclear.

ptsN
protein-Npi-phosphohistidine-sugar phosphotransferase; Probable nitrogen regulatory IIA protein,; High confidence in function and specificity.
 
 
 0.921
hprK
Probable Hpr serine kinase/phosphatase; Catalyzes the ATP- as well as the pyrophosphate-dependent phosphorylation of a specific serine residue in HPr, a phosphocarrier protein of the phosphoenolpyruvate-dependent sugar phosphotransferase system (PTS). HprK/P also catalyzes the pyrophosphate-producing, inorganic phosphate-dependent dephosphorylation (phosphorolysis) of seryl-phosphorylated HPr (P-Ser-HPr).

eno
Putative enolase; Catalyzes the reversible conversion of 2-phosphoglycerate into phosphoenolpyruvate. It is essential for the degradation of carbohydrates via glycolysis; Belongs to the enolase family.

tkt
Putative transketolase; Catalyzes the transfer of a two-carbon ketol group from a ketose donor to an aldose acceptor, via a covalent intermediate with the cofactor thiamine pyrophosphate.
 
 
 0.646
fba
Putative fructose-bisphosphate aldolase; Catalyzes the aldol condensation of dihydroxyacetone phosphate (DHAP or glycerone-phosphate) with glyceraldehyde 3-phosphate (G3P) to form fructose 1,6-bisphosphate (FBP) in gluconeogenesis and the reverse reaction in glycolysis.
  
 
 0.643
pgi
Glucose-6-phosphate isomerase 1(EC 5.3.1.9) (GPI 1)(Phosphoglucose isomerase 1)(PGI 1)(Phosphohexose isomerase 1) (PHI 1). Enzyme involved in glycolysis and in gluconeogenesis.Catalytic activity: d-glucose 6-phosphate = d-fructose 6- phosphate.Belongs to the gpi family. 39% G6P_Isomerase. Pfam:PF00342; PGI; 1; High confidence in function and specificity.
