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

yxkIPutative membrane protease; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme; Belongs to the peptidase M48 family. (562 aa)    
Predicted Functional Partners:
yxzE
Putative bacteriocin; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative factor.

cimH
citrate/malate/H+ symporter; Proton motive force-driven secondary transporter that catalyzes the uptake of both citrate and malate. Appears to be an electroneutral proton-solute symporter; the number of protons transported is equal to the valence of the transported anions. Is strictly stereoselective, translocating only the (S)-enantiomer of malate.

yteT
Putative dehydrogenase of rhamnogalaturonan degradation; May play a role in the degradation of type I rhamnogalacturonan derived from plant cell walls. Belongs to the Gfo/Idh/MocA family.

csfB
Forespore-specific anti-sigma factor; An anti-sigma-G factor, prevents premature activation of sigma-G factor in the forespore; overexpression leads to 1000-fold reduction in spore formation, spore formation stops after engulfment. Overexpression also inhibits sigma- G transcription activation activity. When both Gin and sigma-G are expressed in E.coli Gin inhibits sigma-G, strongly suggesting Gin inhibits by direct physical interaction.

ybcI
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.

btr
HTH-type transcriptional activator Btr; In iron-limited conditions, activates expression of the feuABCybbA operon, which encodes the bacillibactin uptake system. Acts by binding directly to a conserved direct repeat element upstream of the feuA promoter. Activity is increased in the presence of bacillibactin.

grpE
Nucleotide exchange factor for DnaK activity; Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins, in association with DnaK and GrpE. It is the nucleotide exchange factor for DnaK and may function as a thermosensor. Unfolded proteins bind initially to DnaJ; upon interaction with the DnaJ-bound protein, DnaK hydrolyzes its bound ATP, resulting in the formation of a stable complex. GrpE releases ADP from DnaK; ATP binding to DnaK triggers the release of the substrate protein, thus completing the reaction cycle. S [...]
