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:
pagPPhospholipid:lipid A palmitoyltransferase; Transfers a palmitate residue from the sn-1 position of a phospholipid to the N-linked hydroxymyristate on the proximal unit of lipid A or its precursors. Phosphatidylglycerol (PtdGro), phosphatidylethanolamine (PtdEtn), phosphatidylserine (PtdSer) and phosphatidic acid (Ptd-OH) are all effective acyl donors. (186 aa)
yrfFPutative RcsCDB-response attenuator, inner membrane protein; Putative dehydrogenase. (711 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)
speCOrnithine decarboxylase, constitutive; Ornithine decarboxylase isozyme; Protein involved in polyamine biosynthetic process. (711 aa)
speBAgmatinase; Catalyzes the formation of putrescine from agmatine. (306 aa)
rpoSRNA polymerase, sigma S (sigma 38) factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the master transcriptional regulator of the stationary phase and the general stress response. Controls, positively or negatively, the expression of several hundred genes, which are mainly involved in metabolism, transport, regulation and stress management. (330 aa)
fliCFlagellar filament structural protein (flagellin); Flagellin is the subunit protein which polymerizes to form the filaments of bacterial flagella. (498 aa)
slyAGlobal transcriptional regulator; Transcription regulator that can specifically activate or repress expression of target genes. Activates expression of genes such as molecular chaperones (groL, groS, dnaK, grpE, and cbpA), proteins involved in acid resistance (hdeA, hdeB, and gadA), the starvation lipoprotein slp, virulence protein hlyE/clyA. Represses expression of genes involved in the histidine biosynthetic pathway such as hisA, hisB, hisD, hisF and hisG. Required for the activation of virulence genes; Belongs to the SlyA family. (144 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)
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)
speFOrnithine decarboxylase isozyme, inducible; Protein involved in polyamine biosynthetic process; Belongs to the Orn/Lys/Arg decarboxylase class-I family. (732 aa)
