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:
ydgDPutative peptidase; Belongs to the peptidase S1B family. (273 aa)
mdtIMultidrug efflux system transporter; Catalyzes the excretion of spermidine. Can also confer resistance to deoxycholate and SDS; Belongs to the drug/metabolite transporter (DMT) superfamily. Small multidrug resistance (SMR) (TC 2.A.7.1) family. MdtI subfamily. (109 aa)
mdtJMultidrug efflux system transporter; Catalyzes the excretion of spermidine. Can also confer resistance to deoxycholate and SDS; Belongs to the drug/metabolite transporter (DMT) superfamily. Small multidrug resistance (SMR) (TC 2.A.7.1) family. MdtJ subfamily. (121 aa)
tqsAPheromone AI-2 transporter; Controls the transport of the quorum-sensing signal AI-2 either by enhancing its secretion or inhibiting its uptake and consequently represses biofilm formation and motility and affects the global gene expression in biofilms. (344 aa)
plaPPutrescine importer, low affinity; Putrescine importer. Required for induction of type 1 pili- driven surface motility. (452 aa)
evgAResponse regulator in two-component regulatory system with EvgS; Member of the two-component regulatory system EvgS/EvgA. Regulates the expression of emrKY operon and yfdX. Seems also to control expression of at least one other multidrug efflux operon. (204 aa)
cadBPutative lysine/cadaverine transporter; Probable cadaverine/lysine antiporter or part of it. (444 aa)
potDSpermidine/putrescine ABC transporter periplasmic binding protein; Required for the activity of the bacterial periplasmic transport system of putrescine and spermidine. Polyamine binding protein; Belongs to the bacterial solute-binding protein PotD/PotF family. (348 aa)
araCAra regulon transcriptional activator; Transcription factor that regulates the expression of several genes involved in the transport and metabolism of L-arabinose. Functions both as a positive and a negative regulator. In the presence of arabinose, activates the expression of the araBAD, araE, araFGH and araJ promoters. In the absence of arabinose, negatively regulates the araBAD operon. Represses its own transcription. Acts by binding directly to DNA. (292 aa)
speESpermidine synthase (putrescine aminopropyltransferase); Involved in the biosynthesis of polyamines which play a significant role in the structural and functional organization in the chromoid of E.coli by compacting DNA and neutralizing negative charges. Catalyzes the irreversible transfer (ping-pong mechanism) of a propylamine group from the amino donor S-adenosylmethioninamine (decarboxy-AdoMet) to putrescine (1,4-diaminobutane) to yield spermidine. Cadaverine (1,5-diaminopentane) and spermidine can also be used as the propylamine acceptor. (288 aa)
lacZbeta-D-galactosidase; Protein involved in carbohydrate catabolic process; Belongs to the glycosyl hydrolase 2 family. (1024 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)
potFPutrescine ABC transporter periplasmic binding protein; Required for the activity of the bacterial periplasmic transport system of putrescine. Polyamine binding protein. Belongs to the bacterial solute-binding protein PotD/PotF family. (370 aa)
potHPutrescine ABC transporter permease; Required for the activity of the bacterial periplasmic transport system of putrescine; Belongs to the binding-protein-dependent transport system permease family. CysTW subfamily. (317 aa)
potIPutrescine ABC transporter permease; Required for the activity of the bacterial periplasmic transport system of putrescine; Belongs to the binding-protein-dependent transport system permease family. CysTW subfamily. (281 aa)
potCSpermidine/putrescine ABC transporter permease; Required for the activity of the bacterial periplasmic transport system of putrescine and spermidine; Belongs to the binding-protein-dependent transport system permease family. CysTW subfamily. (264 aa)
potBSpermidine/putrescine ABC transporter permease; Required for the activity of the bacterial periplasmic transport system of putrescine and spermidine; Belongs to the binding-protein-dependent transport system permease family. CysTW subfamily. (275 aa)
puuPPutrescine importer; Involved in the uptake of putrescine. Belongs to the amino acid-polyamine-organocation (APC) superfamily. (461 aa)
speGSpermidine N(1)-acetyltransferase; Involved in the protection against polyamine toxicity by regulating their concentration. Catalyzes the transfer of an acetyl group from acetyl coenzyme A (AcCoA) to the primary amino groups of spermidine to yield N(1)- and N(8)-acetylspermidine. It can also use polyamines such as spermine, but not putrescine. (186 aa)
potASpermidine/putrescine ABC transporter ATPase; Part of the ABC transporter complex PotABCD involved in spermidine/putrescine import. Responsible for energy coupling to the transport system. Belongs to the ABC transporter superfamily. Spermidine/putrescine importer (TC 3.A.1.11.1) family. (378 aa)
