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

ydgRPutative POT family peptide transport protein; Proton-dependent permease that transports di- and tripeptides. (501 aa)    
Predicted Functional Partners:
gst
Similar to E. coli glutathionine S-transferase (AAC74707.1); Blastp hit to AAC74707.1 (201 aa), 84% identity in aa 1 - 200.
 
    0.716
ompC
Outer membrane protein 1b (ib;c); Forms pores that allow passive diffusion of small molecules across the outer membrane.
      
 0.499
ompF
Outer membrane protein 1a (ia;b;f), porin; Forms pores that allow passive diffusion of small molecules across the outer membrane. It is also a receptor for the bacteriophage T2 (By similarity).
      
 0.459
csgD
Putative transcriptional regulator; Necessary for transcription of the csgAB operon. May have the capability to respond to starvation and/or high cell density by activating csgBA transcription (By similarity).
      
 0.459
ompR
Response regulator in two-component regulatory system with EnvZ; Member of the two-component regulatory system EnvZ/OmpR involved in osmoregulation (particularly of genes ompF and ompC) as well as other genes (By similarity). Plays a central role in both acid and osmotic stress responses. Binds to the promoter of both ompC and ompF; at low osmolarity it activates ompF transcription, while at high osmolarity it represses ompF and activates ompC transcription (By similarity).
      
 0.459
cycA
APC family D-alanine/D-serine/glycine transport protein; Similar to E. coli transport of D-alanine, D-serine, and glycine (AAC77165.1); Blastp hit to AAC77165.1 (470 aa), 95% identity in aa 1 - 469.
      
 0.452
envZ
Sensory histidine kinase in two-component regulatory system with OmpR; Member of the two-component regulatory system EnvZ/OmpR involved in osmoregulation (particularly of genes ompF and ompC) as well as other genes (By similarity). EnvZ functions as a membrane- associated protein kinase that phosphorylates OmpR in response to environmental signals; at low osmolarity OmpR activates ompF transcription, while at high osmolarity it represses ompF and activates ompC transcription (By similarity).
