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

dltBPutative D-alanine esterase for lipoteichoic acid and wall teichoic acid; Involved in the D-alanylation of lipoteichoic acid (LTA). Could be involved in the transport of activated D-alanine through the membrane. 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. (395 aa)    
Predicted Functional Partners:
dltA
D-alanine:D-alanyl-carrier protein ligase; 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 [...]

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.

dltD
Putative D-alanine esterase for lipoteichoic acid and wall teichoic acid synthesis; 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.

srfAC
Surfactin synthetase; Probably activates a leucine.
 
 
 0.976
pksJ
Polyketide synthase of type I; Involved in some intermediate steps for the synthesis of the antibiotic polyketide bacillaene which is involved in secondary metabolism.
 
 
 0.975
srfAB
Surfactin synthetase; This protein is a multifunctional enzyme able to activate and polymerize the amino acids Leu, Glu, Asp and Val. Activation sites for these AA consist of individual domains.
 
 
 0.971
dhbF
Siderophore 2,3-dihydroxybenzoate-glycine-threonine trimeric ester bacillibactin synthetase; Specifically adenylates threonine and glycine, and loads them onto their corresponding peptidyl carrier domains.
 
 
 0.971
pksN
Polyketide synthase of type I; Involved in some intermediate steps for the synthesis of the antibiotic polyketide bacillaene which is involved in secondary metabolism.
  
 
 0.968
dltE
Putative oxidoreductase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme; Belongs to the short-chain dehydrogenases/reductases (SDR) family.
  
  
 0.925
mprF
Phosphatidylglycerol lysyltransferase involved in lysinylation of phospholipids; Catalyzes the transfer of a lysyl group from L-lysyl- tRNA(Lys) to membrane-bound phosphatidylglycerol (PG), which produces lysylphosphatidylglycerol (LPG), one of the components of the bacterial membrane with a positive net charge. LPG synthesis contributes to the resistance to cationic antimicrobial peptides (CAMPs) and likely protects B.subtilis against its own CAMPs and against those produced by competiting microorganisms (bacteriocins). In fact, the modification of anionic phosphatidylglycerol with po [...]
