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

cstACarbon starvation protein involved in peptide utilization; Involved in peptide utilization during carbon starvation. (701 aa)    
Predicted Functional Partners:
ybdD
DUF466 family protein; To E.coli YjiX.

yjiX
DUF466 family protein; To E.coli YbdD.

putP
Proline:sodium symporter; Catalyzes the sodium-dependent uptake of extracellular L- proline. This protein is also capable of using lithium as the transport cation. Also catalyzes the uptake of propionate.

yehU
Inner membrane putative sensory kinase in two-component system with YehT; Member of the two-component regulatory system BtsS/BtsR, which is part of a nutrient-sensing regulatory network composed of BtsS/BtsR, the low-affinity pyruvate signaling system YpdA/YpdB and their respective target proteins, BtsT and YhjX. Responds to depletion of nutrients, specifically serine, and the concomitant presence of extracellular pyruvate. BtsS is a high-affinity receptor for extracellular pyruvate that activates BtsR by phosphorylation. Activation of the BtsS/BtsR signaling cascade also suppresses Yp [...]

mglB
Methyl-galactoside transporter subunit; This protein is involved in the active transport of galactose and glucose. It plays a role in the chemotaxis towards the two sugars by interacting with the trg chemoreceptor.
   
  
 0.687
csrA
Pleiotropic regulatory protein for carbon source metabolism; A key translational regulator that binds mRNA to regulate translation initiation and/or mRNA stability, initially identified for its effects on central carbon metabolism. Mediates global changes in gene expression, shifting from rapid growth to stress survival by linking envelope stress, the stringent response and the catabolite repression systems. Binds to the 5'-UTR of mRNA to repress or activate translation; 2 binding sites on the homodimer can bridge 2 sites within target RNA (By similarity). Exerts reciprocal effects on [...]

aldA
Aldehyde dehydrogenase A, NAD-linked; Acts on lactaldehyde as well as other aldehydes.
   
  
 0.683
glgC
Glucose-1-phosphate adenylyltransferase; Involved in the biosynthesis of ADP-glucose, a building block required for the elongation reactions to produce glycogen. Catalyzes the reaction between ATP and alpha-D-glucose 1-phosphate (G1P) to produce pyrophosphate and ADP-Glc; Belongs to the bacterial/plant glucose-1-phosphate adenylyltransferase family.
   
  
 0.674
yehT
Putative response regulator in two-component system withYehU; Member of the two-component regulatory system BtsS/BtsR, which is part of a nutrient-sensing regulatory network composed of BtsS/BtsR, the low-affinity pyruvate signaling system YpdA/YpdB and their respective target proteins, BtsT and YhjX. Responds to depletion of nutrients, specifically serine, and the concomitant presence of extracellular pyruvate. BtsR regulates expression of btsT by binding to its promoter region. Activation of the BtsS/BtsR signaling cascade also suppresses YpdA/YpdB-mediated yhjX induction.
  
  
 0.624
acs
acetyl-CoA synthetase; Catalyzes the conversion of acetate into acetyl-CoA (AcCoA), an essential intermediate at the junction of anabolic and catabolic pathways. Acs undergoes a two-step reaction. In the first half reaction, Acs combines acetate with ATP to form acetyl-adenylate (AcAMP) intermediate. In the second half reaction, it can then transfer the acetyl group from AcAMP to the sulfhydryl group of CoA, forming the product AcCoA.
