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:
lpxKTetraacyldisaccharide 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). (325 aa)
pagPPhoPQ-activated gene; 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. Required for resistance to cationic antimicrobial peptides (CAMPs). Modifications of lipid A with a palmitate chain allow to evade host immune defenses by resisting antimicrobial peptides and attenuating the inflammatory response to infection triggered by lipopolysaccharide through the Toll-like receptor 4 (TLR4) signal transduction pathway. (190 aa)
lpxHUDP-2,3-diacylglucosamine hydrolase; 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. (240 aa)
lpxBtetraacyldisaccharide-1-P; 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. (382 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)
lpxDUDP-3-O-(3-hydroxymyristoyl)-glucosamine n-acyltransferase; Catalyzes the N-acylation of UDP-3-O- (hydroxytetradecanoyl)glucosamine using 3-hydroxytetradecanoyl-ACP as the acyl donor. Is involved in the biosynthesis of lipid A, a phosphorylated glycolipid that anchors the lipopolysaccharide to the outer membrane of the cell. (341 aa)
lpxCUDP-3-O-acyl N-acetylglucosamine deacetylase; Catalyzes the hydrolysis of UDP-3-O-myristoyl-N- acetylglucosamine to form UDP-3-O-myristoylglucosamine and acetate, the committed step in lipid A biosynthesis; Belongs to the LpxC family. (305 aa)
yjdBPutative integral membrane protein; 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)
kdtA3-deoxy-D-manno-octulosonic-acid transferase; Involved in lipopolysaccharide (LPS) biosynthesis. Catalyzes the transfer of 3-deoxy-D-manno-octulosonate (Kdo) residue(s) from CMP- Kdo to lipid IV(A), the tetraacyldisaccharide-1,4'-bisphosphate precursor of lipid A; Belongs to the glycosyltransferase group 1 family. (425 aa)
pgtAActivator protein; Member of the two-component regulatory system PgtB/PgtA that regulates the inducible phosphoglycerate transport system. When activated by PgtB it acts in conjunction with sigma-54 as a transcriptional activator. (415 aa)
yeiUPutative permease; Involved in the modification of the lipid A domain of lipopolysaccharides (LPS). Transfers a phosphate group from undecaprenyl pyrophosphate (C55-PP) to lipid A to form lipid A 1- diphosphate. Contributes to the recycling of undecaprenyl phosphate (C55-P); Belongs to the LpxT phosphotransferase family. (239 aa)
msbBMyristoyl transferase in lipid A biosynthesis; Catalyzes the transfer of myristate from myristoyl-acyl carrier protein (ACP) to Kdo(2)-(lauroyl)-lipid IV(A) to form Kdo(2)- lipid A. (323 aa)
htrBLauroyl/myristoyl acyltransferase involved in lipid A biosynthesis; 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). (306 aa)
