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:
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)
speDS-adenosylmethionine decarboxylase; Catalyzes the decarboxylation of S-adenosylmethionine to S- adenosylmethioninamine (dcAdoMet), the propylamine donor required for the synthesis of the polyamines spermine and spermidine from the diamine putrescine. (264 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)
speFOrnithine decarboxylase isozyme, inducible; Protein involved in polyamine biosynthetic process; Belongs to the Orn/Lys/Arg decarboxylase class-I family. (732 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)
speBAgmatinase; Catalyzes the formation of putrescine from agmatine. (306 aa)
nusGTranscription termination factor; Participates in transcription elongation, termination and antitermination. In the absence of Rho, increases the rate of transcription elongation by the RNA polymerase (RNAP), probably by partially suppressing pausing. In the presence of Rho, modulates most Rho-dependent termination events by interacting with the RNAP to render the complex more susceptible to the termination activity of Rho. May be required to overcome a kinetic limitation of Rho to function at certain terminators. Also involved in ribosomal RNA and phage lambda N-mediated transcription [...] (181 aa)
rsmC16S rRNA m(2)G1207 methyltransferase, SAM-dependent; Specifically methylates the guanine in position 1207 of 16S rRNA in the 30S particle. (343 aa)
