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:
eptALipid A phosphoethanolamine transferase; Catalyzes the addition of a phosphoethanolamine moiety to the lipid A. The phosphoethanolamine modification is required for resistance to polymyxin; Belongs to the phosphoethanolamine transferase family. EptA subfamily. (547 aa)
basRResponse regulator in two-component regulatory system with BasS; Member of the two-component regulatory system BasS/BasR. BasR induces the transcription of the ugd, ais, arnBCADTEF and eptA-basRS loci, all involved in resistance to polymyxin (By similarity). (222 aa)
phoQSensory histidine kinase in two-component regulatory system with PhoP; Member of the two-component regulatory system PhoP/PhoQ involved in adaptation to low Mg(2+) environments and the control of acid resistance genes. In low periplasmic Mg(2+), PhoQ functions as a membrane-associated protein kinase that undergoes autophosphorylation and subsequently transfers the phosphate to PhoP, resulting in the expression of PhoP-activated genes (PAG) and repression of PhoP- repressed genes (PRG). In high periplasmic Mg(2+), acts as a protein phosphatase that dephosphorylates phospho-PhoP, resulti [...] (486 aa)
phoPResponse regulator in two-component regulatory system with PhoQ; Member of the two-component regulatory system PhoP/PhoQ involved in adaptation to low Mg(2+) environments and the control of acid resistance genes. In low periplasmic Mg(2+), PhoQ phosphorylates PhoP, resulting in the expression of PhoP-activated genes (PAG) and repression of PhoP-repressed genes (PRG). In high periplasmic Mg(2+), PhoQ dephosphorylates phospho-PhoP, resulting in the repression of PAG and may lead to expression of some PRG (By similarity). Mediates magnesium influx to the cytosol by activation of MgtA. Pro [...] (223 aa)
mgrBRegulatory peptide for PhoPQ, feedback inhibition; Represses PhoP/PhoQ signaling, possibly by binding to the periplasmic domain of PhoQ, altering its activity and that of downstream effector PhoP. PhoP-regulated transcription is redox- sensitive, being activated when the periplasm becomes more reducing (deletion of dsbA/dsbB, treatment with dithiothreitol). MgrB acts between DsbA/DsbB and PhoP/PhoQ in this pathway; the 2 periplasmic Cys residues of MgrB are required for its action on PhoQ, and thus PhoP. (47 aa)
arnT4-amino-4-deoxy-L-arabinose transferase; Catalyzes the transfer of the L-Ara4N moiety of the glycolipid undecaprenyl phosphate-alpha-L-Ara4N to lipid A. The modified arabinose is attached to lipid A and is required for resistance to polymyxin and cationic antimicrobial peptides. (550 aa)
pmrDInactive two-component system connector protein; Interacts with phosphorylated BasR protein to mediate transcriptional induction of BasR-activated genes to induce polymyxin resistance in some natural isolates; Belongs to the PmrD family. (88 aa)
rpsL30S ribosomal subunit protein S12; With S4 and S5 plays an important role in translational accuracy. Cryo-EM studies suggest that S12 contacts the EF-Tu bound tRNA in the A-site during codon-recognition. This contact is most likely broken as the aminoacyl-tRNA moves into the peptidyl transferase center in the 50S subunit; Belongs to the universal ribosomal protein uS12 family. (124 aa)
basSSensory histidine kinase in two-component regulatory system with BasR; Member of the two-component regulatory system BasS/BasR Autophosphorylates and activates BasR by phosphorylation. (363 aa)
