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:
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)
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)
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)
lpxLLauryl-acyl carrier protein (ACP)-dependent acyltransferase; Catalyzes the transfer of laurate from lauroyl-acyl carrier protein (ACP) to Kdo(2)-lipid IV(A) to form Kdo(2)-(lauroyl)-lipid IV(A). Has 10 fold selectivity for lauroyl-ACP over myristoyl-ACP. In vitro, can also catalyze a slow second acylation reaction leading to the formation of Kdo(2)-(dilauroyl)-lipid IV(A). (306 aa)
lpxBtetraacyldisaccharide-1-P synthase; Condensation of UDP-2,3-diacylglucosamine and 2,3- diacylglucosamine-1-phosphate to form lipid A disaccharide, a precursor of lipid A, a phosphorylated glycolipid that anchors the lipopolysaccharide to the outer membrane of the cell; Belongs to the LpxB family. (382 aa)
lpxHUDP-2,3-diacylglucosamine pyrophosphohydrolase; Hydrolyzes the pyrophosphate bond of UDP-2,3- diacylglucosamine to yield 2,3-diacylglucosamine 1-phosphate (lipid X) and UMP by catalyzing the attack of water at the alpha-P atom. Involved in the biosynthesis of lipid A, a phosphorylated glycolipid that anchors the lipopolysaccharide to the outer membrane of the cell. Is essential for E.coli growth. Does not cleave the unacylated UDP-GlcNAc, the mono-acylated UDP-3-O-(R)-3- hydroxymyristoyl-GlcNAc, and CDP-diacylglycerol. Belongs to the LpxH family. (240 aa)
lpxKLipid A 4'kinase; Transfers the gamma-phosphate of ATP to the 4'-position of a tetraacyldisaccharide 1-phosphate intermediate (termed DS-1-P) to form tetraacyldisaccharide 1,4'-bis-phosphate (lipid IVA). (328 aa)
lpxAUDP-N-acetylglucosamine acetyltransferase; Involved in the biosynthesis of lipid A, a phosphorylated glycolipid that anchors the lipopolysaccharide to the outer membrane of the cell. (262 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)
kdgRKDG regulon transcriptional repressor; Transcriptional regulator of the kdgK gene for the kdg kinase and the kdgT gene for the kdg permease. (263 aa)
lpxMMyristoyl-acyl carrier protein (ACP)-dependent acyltransferase; Catalyzes the transfer of myristate from myristoyl-acyl carrier protein (ACP) to Kdo(2)-(lauroyl)-lipid IV(A) to form Kdo(2)- lipid A. Can probably also catalyze the transfer of myristate to Kdo(2)-(palmitoleoyl)-lipid IV(A) to form the cold-adapted Kdo(2)-lipid A. In vitro, can acylate Kdo(2)-lipid IV(A), but acylation of (KDO)2- (lauroyl)-lipid IV(A) is about 100 times faster. In vitro, can use lauroyl-ACP but displays a slight kinetic preference for myristoyl-ACP. (323 aa)
ugdUDP-glucose 6-dehydrogenase; Protein involved in cell surface antigen activity, host-interacting, colanic acid biosynthetic process and response to desiccation. (388 aa)
arnBUridine 5'-(beta-1-threo-pentapyranosyl-4-ulose diphosphate) aminotransferase, PLP-dependent; Catalyzes the conversion of UDP-4-keto-arabinose (UDP-Ara4O) to UDP-4-amino-4-deoxy-L-arabinose (UDP-L-Ara4N). The modified arabinose is attached to lipid A and is required for resistance to polymyxin and cationic antimicrobial peptides. (379 aa)
waaA3-deoxy-D-manno-octulosonic-acid transferase (KDO transferase); Involved in lipopolysaccharide (LPS) biosynthesis. Catalyzes the transfer of two 3-deoxy-D-manno-octulosonate (Kdo) residues from CMP-Kdo to lipid IV(A), the tetraacyldisaccharide-1,4'-bisphosphate precursor of lipid A; Belongs to the glycosyltransferase group 1 family. Glycosyltransferase 30 subfamily. (425 aa)
