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

lpqBProbable conserved lipoprotein LpqB; May modulate activity of the MtrAB system in controlling homeostasis of the cell wall and cell division (By similarity). Partially restores antibiotic resistance to M.smegmatis in which this gene has been disrupted. (583 aa)    
Predicted Functional Partners:
mtrB
Two component sensory transduction histidine kinase MtrB; Member of the two-component regulatory system MtrA/MtrB. Probably functions as a membrane-associated protein kinase that phosphorylates MtrA in response to environmental signals. Autophosphorylates and transfers phosphate to MtrA in vitro. Overexpression of MtrA alone decreases bacterial virulence in mouse infection; co-expression of MtrA and MtrB restores normal bacterial growth, suggesting that bacterial growth in macrophages requires an optimal ratio of MtrB to MtrA. Probably plays a role in cell division.

mtrA
Two component sensory transduction transcriptional regulatory protein MtrA; Member of the two-component regulatory system MtrA/MtrB. Binds direct repeat motifs of sequence 5'-GTCACAGCG-3', phosphorylation confers higher affinity. Overexpression decreases bacteria viability upon infection of human THP-1 macrophage cell line, due at least in part to impaired blockage of phagosome-lysosome fusion (upon infection bacteria usually remain in phagosomes). Infecting C57BL/6 mice with an overexpressing strain leads to an attentuated infection in both spleen and lungs. The level of dnaA mRNA inc [...]

lpqW
Probable conserved lipoprotein LpqW; May directly or indirectly regulate the accessibility of the key branch point intermediate, monoacyl phosphatidylinositol tetramannoside (AcPIM4), to the elongating alpha-1,6 mannosyltransferases which could regulate the lipoarabinomannans (LAMs) biosynthesis; Belongs to the bacterial solute-binding protein 5 family.
