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
Your Input:
cadCcadBA operon transcriptional activator; Required for Pcad induction, a promoter upstream of cadBA that is responsible for the pH-regulated expression of CadA and CadB. Probably acts as an activating transcription factor. (512 aa)
ldcCLysine decarboxylase 2, constitutive; Plays a role in lysine utilization by acting as a lysine decarboxylase. (713 aa)
dnaQDNA polymerase III epsilon subunit; DNA polymerase III is a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria. The epsilon subunit contain the editing function and is a proofreading 3'- 5' exonuclease. Contacts both the beta sliding clamp (dnaN) and the polymerase subunit (dnaE), stabilizing their interaction. (243 aa)
acrAMultidrug efflux system; AcrA-AcrB-AcrZ-TolC is a drug efflux protein complex with broad substrate specificity that uses the proton motive force to export substrates. This subunit may act as an adapter protein that links AcrB and TolC stably together. It is elongated in shape, being long enough to span the periplasm. (397 aa)
potEPutrescine transporter PotE; Catalyzes both the uptake and excretion of putrescine. The uptake of putrescine is dependent on the membrane potential and the excretion involves putrescine-ornithine antiporter activity. (439 aa)
speFOrnithine decarboxylase isozyme, inducible; Protein involved in polyamine biosynthetic process; Belongs to the Orn/Lys/Arg decarboxylase class-I family. (732 aa)
folMDihydromonapterin reductase, NADPH-dependent; Catalyzes the reduction of dihydromonapterin to tetrahydromonapterin. Also has lower activity with dihydrofolate. (240 aa)
ygeRtRNA-Gly; Anticodon: CCC; Belongs to the peptidase M23B family. (251 aa)
lysSLysine tRNA synthetase, constitutive; suppressor of ColE1 mutation in primer RNA; Protein involved in tRNA aminoacylation for protein translation; Belongs to the class-II aminoacyl-tRNA synthetase family. (505 aa)
argPHTH-type transcriptional regulator ArgP; Controls the transcription of genes involved in arginine and lysine metabolism. Activates transcription of several genes, including argO, lysP, lysC, asd, dapB, dapD, lysA, gdhA and argK. Acts by binding directly to their promoter or control region. ArgP dimer by itself is able to bind the argO promoter-operator region to form a binary complex, but the formation of a ternary complex with RNA polymerase is greatly stimulated only in presence of a coeffector. Both arginine and lysine are coeffectors at the argO promoter, but only arginine is compe [...] (297 aa)
tktATransketolase 1, thiamine triphosphate-binding; 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. Thus, catalyzes the reversible transfer of a two-carbon ketol group from sedoheptulose-7-phosphate to glyceraldehyde-3-phosphate, producing xylulose-5-phosphate and ribose- 5-phosphate. (663 aa)
waaOUDP-D-galactose:(glucosyl)lipopolysaccharide- alpha-1,3-D-galactosyltransferase; Protein involved in cell surface antigen activity, host-interacting; Belongs to the glycosyltransferase 8 family. (339 aa)
lysULysine tRNA synthetase, inducible; Also can synthesize a number of adenyl dinucleotides (in particular AppppA). These dinucleotides have been proposed to act as modulators of the heat-shock response and stress response; Belongs to the class-II aminoacyl-tRNA synthetase family. (505 aa)
cadALysine decarboxylase, acid-inducible; Inducible lysine decarboxylase that catalyzes the proton- dependent decarboxylation of L-lysine to produce the polyamine cadaverine and carbon dioxide. Plays a role in pH homeostasis by consuming protons and neutralizing the acidic by- products of carbohydrate fermentation. Belongs to the Orn/Lys/Arg decarboxylase class-I family. (715 aa)
cadBPutative lysine/cadaverine transporter; Probable cadaverine/lysine antiporter or part of it. (444 aa)
ampCPenicillin-binding protein; This protein is a serine beta-lactamase with a substrate specificity for cephalosporins; Belongs to the class-C beta-lactamase family. (377 aa)
treBTrehalose-specific PTS enzyme: IIB and IIC component; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. This system is involved in trehalose transport at low osmolarity. (473 aa)
treRTrehalose 6-phosphate-inducible trehalose regulon transcriptional repressor; Repressor of the treBC operon. It is able to bind trehalose- 6-phosphate and trehalose. (315 aa)
