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

dltDExtramembranal protein; Involved in the D-alanylation of lipoteichoic acid (LTA). Could be responsible for the transfer of DltC-carried D-alanyl groups to cell membrane phosphatidylglycerol (PG), or alternatively of D- alanine residues from D-Ala-undecaprenol phosphate to the poly(glycerophosphate) chains of LTA. D-alanylation of LTA plays an important role in modulating the properties of the cell wall in Gram- positive bacteria, influencing the net charge of the cell wall. (391 aa)    
Predicted Functional Partners:
ABD29324.1
Conserved hypothetical protein; Belongs to the ATP-dependent AMP-binding enzyme family.
 
  
 0.999
dltA
D-alanine-activating enzyme; Catalyzes the first step in the D-alanylation of lipoteichoic acid (LTA), the activation of D-alanine and its transfer onto the D- alanyl carrier protein (Dcp) DltC. In an ATP-dependent two-step reaction, forms a high energy D-alanyl-AMP intermediate, followed by transfer of the D-alanyl residue as a thiol ester to the phosphopantheinyl prosthetic group of the Dcp. D-alanylation of LTA plays an important role in modulating the properties of the cell wall in Gram-positive bacteria, influencing the net charge of the cell wall. Belongs to the ATP-dependent AMP [...]

ABD29995.1
dltB protein, putative; Could be involved in the transport of activated D-alanine through the membrane.
 
 
 0.999
dltC
D-alanyl carrier protein; Carrier protein involved in the D-alanylation of lipoteichoic acid (LTA). The loading of thioester-linked D-alanine onto DltC is catalyzed by D-alanine--D-alanyl carrier protein ligase DltA. The DltC- carried D-alanyl group is further transferred to cell membrane phosphatidylglycerol (PG) by forming an ester bond, probably catalyzed by DltD. D-alanylation of LTA plays an important role in modulating the properties of the cell wall in Gram-positive bacteria, influencing the net charge of the cell wall.

mprF
Conserved hypothetical protein; Catalyzes the transfer of a lysyl group from L-lysyl- tRNA(Lys) to membrane-bound phosphatidylglycerol (PG), which produces lysylphosphatidylglycerol (LPG), a major component of the bacterial membrane with a positive net charge. LPG synthesis contributes to bacterial virulence as it is involved in the resistance mechanism against cationic antimicrobial peptides (CAMP) produces by the host's immune system (defensins, cathelicidins) and by the competing microorganisms (bacteriocins). In fact, the modification of anionic phosphatidylglycerol with positively [...]

ltaS
Conserved hypothetical protein; Catalyzes the polymerization of lipoteichoic acid (LTA) polyglycerol phosphate, a reaction that presumably uses phosphatidylglycerol (PG) as substrate. Is required for staphylococcal growth and cell division process; Belongs to the LTA synthase family.

acpP
Acyl carrier protein; Carrier of the growing fatty acid chain in fatty acid biosynthesis.
  
  
 0.640
ugtP
Conserved hypothetical protein; Processive glucosyltransferase involved in the biosynthesis of both the bilayer- and non-bilayer-forming membrane glucolipids. Is able to successively transfer two glucosyl residues to diacylglycerol (DAG), thereby catalyzing the formation of beta-monoglucosyl-DAG (3-O- (beta-D-glucopyranosyl)-1,2-diacyl-sn-glycerol) and beta-diglucosyl-DAG (3-O-(beta-D-glucopyranosyl-beta-(1->6)-D-glucopyranosyl)-1,2-diacyl- sn-glycerol). Beta-diglucosyl-DAG is the predominant glycolipid found in Bacillales and is also used as a membrane anchor for lipoteichoic acid (LT [...]
