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

hpf
Sigma 54 modulation protein/ribosomal protein S30EA; Required for dimerization of active 70S ribosomes into 100S ribosomes in stationary phase; 100S ribosomes are translationally inactive and sometimes present during exponential growth.
  
  
 0.816
GM21_3384
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).

GM21_1703
KEGG: gbm:Gbem_2516 PTSINtr with GAF domain, PtsP; TIGRFAM: phosphoenolpyruvate-protein phosphotransferase; PFAM: PEP-utilizing protein; PEP-utilising protein domain protein; PEP-utilising protein mobile region; GAF domain protein; SMART: GAF domain protein; Belongs to the PEP-utilizing enzyme family.

GM21_3386
PFAM: PTS system fructose subfamily IIA component; KEGG: gbm:Gbem_0873 PTS system fructose subfamily IIA component.
 
  
 0.708
GM21_3390
RNA polymerase, sigma 54 subunit, RpoN; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
 
  
 0.664
hprK
HPr kinase; 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).
