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

mprFPhosphatidylglycerol 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 [...] (856 aa)    
Predicted Functional Partners:
clsA
Cardiolipin synthase; Catalyzes the reversible phosphatidyl group transfer from one phosphatidylglycerol molecule to another to form cardiolipin (CL) (diphosphatidylglycerol) and glycerol; Belongs to the phospholipase D family. Cardiolipin synthase subfamily.

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 [...]

ugtP
UDP-glucose diacylglyceroltransferase; Processive glucosyltransferase involved in the biosynthesis of both the bilayer- and non-bilayer-forming membrane glucolipids. Is able to successively transfer up to three glucosyl residues to diacylglycerol (DAG), thereby catalyzing the formation of beta- monoglucosyl-DAG (3-O-(beta-D-glucopyranosyl)-1,2-diacyl-sn-glycerol), beta-diglucosyl-DAG (3-O-(beta-D-glucopyranosyl-beta-(1->6)-D- glucopyranosyl)-1,2-diacyl-sn-glycerol) and beta-triglucosyl-DAG (3-O- (beta-D-glucopyranosyl-beta-(1->6)-D-glucopyranosyl-beta-(1->6)-D- glucopyranosyl)-1,2-diac [...]

walK
Two-component sensor histidine kinase [YycG]; Member of the two-component regulatory system WalK/WalR involved in the regulation of the ftsAZ operon, the yocH and ykvT, cwlO, lytE, ydjM, yjeA, yoeB genes and the tagAB and tagDEF operons. Phosphorylates WalR.
  
  
 0.829
rpoC
RNA polymerase (beta' subunit); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
      
 0.826
dltB
Putative 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.

rpoB
RNA polymerase (beta subunit); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.

ltaSA
Exported glycerol phosphate lipoteichoic acid synthetase and anion-binding protein; Catalyzes the polymerization of lipoteichoic acid (LTA) polyglycerol phosphate, a reaction that presumably uses phosphatidylglycerol (PG) as substrate.

liaF
Integral inner membrane protein; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type m: membrane component.
   
  
 0.767
ytxK
Putative nucleic acid methyltransferase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme; To type I restriction system adenine methylases.
