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

lytSTwo-component sensor histidine kinase, putative; Member of the two-component regulatory system LytR/LytS that regulates genes involved in autolysis, programmed cell death, biofilm formation and cell wall metabolism. Participates also in sensing and responding to host defense cationic antimicrobial peptides (CAMPs). Functions as a sensor protein kinase which is autophosphorylated at a histidine residue and transfers its phosphate group to the conserved aspartic acid residue in the regulatory domain of LytR. In turn, LytR binds to the upstream promoter regions of target genes including l [...] (579 aa)    
Predicted Functional Partners:
lytR
Two-component response regulator, putative; Member of the two-component regulatory system LytR/LytS that regulates genes involved in autolysis, programmed cell death, biofilm formation and cell wall metabolism. Participates also in sensing and responding to host defense cationic antimicrobial peptides (HDPs). Upon phosphorylation by LytS, functions as a transcription regulator by direct binding to promoter regions of target genes including lrgA and lrgB, to positively regulate their expression.

lrgA
Conserved hypothetical protein; Inhibits the expression or activity of extracellular murein hydrolases by interacting, possibly with LrgB, with the holin-like proteins CidA and/or CidB. The LrgAB and CidAB proteins may affect the proton motive force of the membrane. Increases tolerance to penicillin possibly by inhibiting the formation of the CidAB holin-like complexes within the membrane, thus reducing penicillin-induced lethality. Possibly plays a role in programmed cell death (PCD), triggering PCD in response to penicillin, and possibly other antibiotics, and environmental stresses.

lrgB
Holin-like protein LrgB, putative; Inhibits the expression or activity of extracellular murein hydrolases by interacting, possibly with LrgA, with the holin-like proteins CidA and/or CidB. The LrgAB and CidAB proteins may affect the proton motive force of the membrane. Increases tolerance to penicillin possibly by inhibiting the formation of the CidAB holin-like complexes within the membrane, thus reducing penicillin-induced lethality. Possibly plays a role in programmed cell death (PCD), triggering PCD in response to penicillin, and possibly other antibiotics, and environmental stresses.

Conserved hypothetical protein.
  
 0.682
cidB
Conserved hypothetical protein; Increases the activity of extracellular murein hydrolases possibly by mediating their export via hole formation. Inhibited by the antiholin-like proteins LrgAB. In an unstressed cell, the LrgAB products probably inhibit the function of the CidAB proteins. When a cell is stressed by the addition of antibiotics or by other factors in the environment, the CidAB proteins possibly oligomerize within the bacterial cell membrane, creating lesions that disrupt the proton motive force, which in turn results in loss of cell viability. These lesions are also hypoth [...]

hptS
Conserved hypothetical protein; Member of the two-component regulatory system HptS/HptR that regulates genes involved in hexose phosphate transport system in response to changes in extracellular phosphate sources. May act as a sensor protein kinase which is autophosphorylated at a histidine residue and transfers its phosphate group to the conserved aspartic acid residue in the regulatory domain of HptS. In turn, HptS antagonizes CcpA-dependent transcription of a subset of CcpA-regulated genes involved in antibiotic susceptibility.
 
  
0.627
hptR
Response regulator receiver domain protein; Member of the two-component regulatory system HptS/HptR that regulates genes involved in hexose phosphate transport system in response to changes in extracellular phosphate sources. Activates uhpT expression to facilitate glucose-6- phosphate/G6P utilization by directly binding to its promoter. Antagonizes CcpA-dependent transcription of a subset of CcpA-regulated genes involved in antibiotic susceptibility.
