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

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 [...]

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.
  
    0.761
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.

ndoAI
Antitoxin EndoAI; Antitoxin component of a type II toxin-antitoxin (TA) system. Antitoxin that directly inhibits activity of EndoA in vitro. Upon expression in E.coli counteracts inhibitory effect of endoribonuclease EndoA. The EndoA-EndoAI complex does not seem to bind its own promoter.

pta
Phosphotransacetylase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme.
   
    0.502
hfq
Hfq RNA chaperone; RNA chaperone that binds small regulatory RNA (sRNAs) and mRNAs to facilitate mRNA translational regulation in response to envelope stress, environmental stress and changes in metabolite concentrations. Also binds with high specificity to tRNAs. Belongs to the Hfq family.
   
    0.501
recU
Holliday junction resolvase; Has at least 2 separable functions; Holliday junction resolution with generation of monomeric chromosomes, and modulation of RecA activity. Endonuclease that resolves Holliday junction intermediates in genetic recombination. Cleaves mobile four-strand junctions by introducing symmetrical nicks in paired strands. Promotes annealing of linear ssDNA with homologous dsDNA. Required for DNA repair, homologous recombination and chromosome segregation. Partially inhibits the hydrolysis of dATP or rATP by RecA. Holliday junction resolution is stimulated by RuvB.
   
    0.501
sspA
Small acid-soluble spore protein (alpha-type SASP); SASP are bound to spore DNA. They are double-stranded DNA- binding proteins that cause DNA to change to an a-like conformation. They protect the DNA backbone from chemical and enzymatic cleavage and are thus involved in dormant spore's high resistance to UV light.
   
    0.501
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.
