STRINGSTRING
STRING protein interaction network
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

lpxPPalmitoleoyl-acyl carrier protein (ACP)-dependent acyltransferase; Catalyzes the transfer of palmitoleate from palmitoleoyl-acyl carrier protein (ACP) to Kdo(2)-lipid IV(A) to form Kdo(2)- (palmitoleoyl)-lipid IV(A). Required for the biosynthesis of a distinct molecular species of lipid A, which is present only in cells grown at low temperatures. It may confer a selective advantage to cells growing at lower temperatures by making the outer membrane a more effective barrier to harmful chemicals. (306 aa)    
Predicted Functional Partners:
waaA
3-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.

lpxM
Myristoyl-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.
  
 
0.949
lpxL
Lauryl-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).
  
 
0.906
lpxD
UDP-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. Prefers (3R)-3-hydroxytetradecanoyl-ACP over (3R)-3-hydroxyhexadecanoyl-ACP as the acyl donor in vitro, which is consistent with the structure of E.coli lipid A that contains over 95% (R)-3-hydroxytetradecanoate at the 2 and 2' positions. Belongs to the transferase [...]
 
   
 0.903
lpxB
tetraacyldisaccharide-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.
 
   
 0.893
argD
Bifunctional acetylornithine aminotransferase and succinyldiaminopimelate aminotransferase; Involved in both the arginine and lysine biosynthetic pathways; Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family. ArgD subfamily.
      
 0.893
lpxK
Lipid 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).
 
  
 0.849
lpxA
UDP-N-acetylglucosamine acetyltransferase; Involved in the biosynthesis of lipid A, a phosphorylated glycolipid that anchors the lipopolysaccharide to the outer membrane of the cell.
 
   
 0.842
ccmB
Heme export ABC transporter permease; Required for the export of heme to the periplasm for the biogenesis of c-type cytochromes.
      
 0.810
lpxC
UDP-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.
